Many motorists were faced with the fact that the muffler burns out, and some simply crumpled it or tore it off. Of course, wear is associated with the operation and performance of the engine. It is worth remembering that the more you drive, the faster the muffler will speak. It is not so difficult to replace it on Renault Logan, given that the design of the car is quite simple.
To replace the Renault Logan muffler, you will need full access from the bottom of the car. This is done for ease of use and correct installation of parts.
So, you can easily and simply change the muffler to Renault Logan.
Replacing the middle part of the Renault Logan muffler is slightly different. Since there are two variants of the exhaust system, consider both. In order to make repairs and replacements, you will have to settle in with a "grinder" and a welding machine.
Some car enthusiasts are tuning Renault Logan, including the exhaust system. So, there are several options for mufflers. The simplest and most affordable is direct flow. It does not require any alteration of the mountings and fits into standard seats.
The second option is tuning for two pipes. So, in the middle part, instead of one branch, there are two. Accordingly, there will now be two mufflers. Moreover, for one there are fastenings, and for the second you will have to do it. More precisely, not the mounts themselves, but the rubber hooks that hold the muffler.
Option three - installing a sports exhaust system. To do this, not one pipe comes out of the "pants", but two. Accordingly, all mounts will have to be redone for a new muffler. To do this, special "ears" are welded on, to which the exhaust system is bolted. It must be rigidly fixed, as opposed to a simple system.
When choosing a muffler, it is worth considering the quality of the material of execution. This will determine how long he will last, his entire resource or will quickly burn out. The best option is to install the original factory production.But, there are analogues that are in no way inferior in quality to those made at the Renault plant.
So, consider the articles and analogues of the muffler that can be installed by Renault Logan.
The second option is to install analogs, the quality of which is also good, but the price is slightly cheaper.
At the same time, this part also has analogues that experts recommend for installation on Renault Logan.
There are several ways to diagnose the failure of a Renault Logan muffler.
Replacing the Renault Logan muffler is a fairly simple and not complicated procedure. Of course, it is better when performing operations to have an assistant who will help you to remove and install the elements of the exhaust system. This is necessary for convenience and when installing the clamps.

Before replacing
Removing the muffler
Installing a new element
The muffler consists of three main parts: the front, which has a catalyst, the middle (or, as it is also called, the resonator part) and the rear.
The exhaust system includes the following parts:
exhaust manifold;
intake pipe;
catalytic converter of exhaust gases;
the actual mufflers (main and additional);
connecting pipes.
The entire unit is attached to the body from below with three special fasteners - rubber cushions.
Heat shields are installed over the two mufflers and the neutralizer, and a metal gasket is placed between the cylinder head and the exhaust manifold. The catalytic converter and the middle part of the muffler are one-piece, non-separable units of the machine. If they become unusable, they must be replaced with new parts.
If, while driving, you find a decrease in engine power, too loud exhaust noise, unusual color of smoke from the exhaust pipe (white, brown or black), you suspect that exhaust gases enter the engine oil system - it is quite possible that it is time to replace the muffler with your Renault Logan. An accurate diagnosis can be made after a detailed inspection of the machine assembly. If it is all covered with corrosion, then the repair of its individual parts cannot be dispensed with, it is necessary to carry out a complete replacement.
So, if repair of the Renault Logan muffler is impossible, it should be replaced. The advantage of the car brand is that you can do it yourself, without resorting to the services of specialists.
Before looking under the car and removing the exhaust system, you should check its tightness and try to determine the nature of the breakdown.
It is also worth running your hand along the entire length of the system to check for subtle leaks.
Then you need to carefully inspect the corrugation and the attachment points of the system to the body. The Renault Logan muffler mounts are rubber cushions that absorb the exhaust system while driving. If they become unusable, then a knock is heard when driving - the parts come into contact with the body, damage it or deform themselves.
Next, you need to decide how to remove the muffler on the Renault Logan. The rubber rivets are removed first, starting at the rear of the muffler. After that, it is necessary to unscrew the fastening bolts on the front pipe, lubricate and remove the fasteners.
The next step is to dismantle the flue gas sensor. Its fasteners are removed by pressing the detachable flag. But if a lambda probe (a device for determining oxygen in exhaust gases) is installed on the car, you must first remove it with a 22 mm key.
Then we move on to the mountings of the middle part of the system. The process of their removal is the same, but before that it is recommended to lower the body bracket and the beam so that the muffler can be lowered and it does not damage other parts of the machine.
The front is removed last and with extreme caution. Here you need to remove the rear shock absorber, and from it the spring so as not to damage the brake hose or the ABS sensor. On this question, how to remove the exhaust pipe on Renault Logan is exhausted and you can start installing a new part.
If only one unit of the system will be replaced, it is necessary to apply marks along which a new part will be removed and then mounted. The replaced element is cut off with a grinder, and then in these places a new one is installed by welding
Installing a new element is easy, especially knowing how the muffler is attached. It is enough to carry out the steps in the reverse order: install the lambda probes, if necessary, insert and fix the muffler, adjust and fix the beam.
Make sure that all parts are clearly in place and that installation is carried out without excessive tension. After installation, you need to check the system for leaks. To do this, at low speed or idle, listen to the operation of the machine, and when it cools down, inspect it. If the noise does not reappear and the assembly itself is not leaking, the repair was successful.
As you can see, it is easy to repair the exhaust system on your own at Renault Logan. It is enough to start the car on a lift or overpass and carry out all the necessary work. For them, you will need an assistant, since the entire system weighs about 30 kg and it will be extremely difficult to remove it carefully yourself. But if you need to replace one part, and you have no welding experience, it is better to leave the solution of this issue to the specialists of the car service.
I came to visit my parents, and my father and I hung out in the garage for 2 days. In 2 days it was done:
Well, now about everything in order. I changed the oil, tk. I have already run 10 thousand, I think it's time, the machine feels when it is well treated, filled in eneos with semi-synthetics, a familiar master advised, because the mileage of the car is almost 120, after the replacement the engine started running quieter.
Replaced the right headlight, because the native turned yellow and is not regulated, the lights in front of the bumper are 1 meter. The headlight is a Taiwanese analogue, it was bought for an incredibly small 1400 r (there is a special offer in the store, all at wholesale prices). On the advice of the seller, I coated the contour with a transparent sealant, so, just for everyone happening.
The main problem was eliminated - the intake pipe of the collector was replaced. The car roared strongly, like a forward flow, during the inspection it was established that the hana came to the cup in which the gasket was put. It was not possible to find the cup separately. I bought this pipe in the same store where the headlight was, I gave 1800 rubles. We tried to make a cup ourselves with my father, but nothing came of it. They cut off a piece of the old pipe, then the same piece from the new one, welded a piece of pipe of a slightly larger diameter onto the new pipe, then inserted the pipe into its place, put a new gasket, tightened the hairpin , scalded the pipe, well, that's it, the roar passed, I'm happy).
A failed muffler can cause a lot of trouble for the car owner. And the Renault Logan driver is no exception. Fortunately, the muffler can be repaired by hand. And for this you absolutely do not need to go to the nearest car service. Let's figure out exactly how this is done.
Even a novice driver can understand that the car's muffler is out of order.
Here are the main signs of problems with this device:
the smell of exhaust gases appeared in the cabin;
engine power has noticeably decreased for no apparent reason;
the engine started to run very loudly;
the noisy operation of the engine is accompanied by loud claps, similar to pistol shots.
Most of the above signs indicate that a hole has formed in the device due to thermal corrosion. A decrease in power is observed due to clogging of the resonator or catalyst of the machine. Alternatively, the smallest holes in the "honeycomb" of the catalyst can simply coke due to prolonged exposure to high temperatures. And the temperature, in turn, rises as a result of the combustion of low-quality fuel. Finally, pistol shots are the result of air entering the vehicle's fuel system. Among these malfunctions, the breakdown of the muffler mounts stands apart. Let's consider it in more detail.
The characteristic thud that comes from under the bottom of the Renault Logan while driving, says only one thing: the muffler mount needs to be replaced. The mechanism hangs under the bottom of the machine on two brackets covered with special abrasion resistant rubber.
But even such rubber can wear out after 100 thousand kilometers.
After that, the device begins to dangle in the bracket and knock on the bottom of the car. It is not possible to restore the worn-out rubber somehow. In any case, in a garage. So there is only one option: buying new rubberized brackets and installing them in place of the old ones.
You need to purchase 2 brackets for the Renault Logan muffler at the auto shop. The best option would be to buy Sasic products (catalog number 40015–80). The cost of these brackets varies from 580 to 750 rubles.
The car is installed on an inspection pit or on an overpass. A 10 spanner wrench unscrews a pair of fastening bolts on the front bracket. The same wrench unscrews a pair of bolts on the rear bracket.
The brackets are removed, replaced with new ones, the bolts are screwed into place.
Between the main muffler and the resonator of the Renault Logan there is a pipe, at the junction of which a special gasket is installed. Thanks to this joint, the silencer does not need to be removed entirely: if the resonator breaks down, only it can be removed. The main body of the device can also be removed separately. This is convenient, but the joint on the pipe and the gasket are the weakest points in the structure. The gasket very often burns out, after which the pipe at the joint begins to dangle and knock. To replace it, you need the following tools:
new gasket for Renault Logan;
socket head for 10 with a long crank;
long chisel;
liquid WD40;
hammer.
The car is installed on an inspection pit, wheel chocks are installed under the wheels.
The bolts holding the gasket are very often corroded. Therefore, they are treated with WD40 liquid, which will facilitate their loosening.
After processing, the bolts on the gasket are unscrewed with a socket head by 10, the joint on the muffler pipe is disconnected.
Access to the old gasket is opened. If it is burnt to the pipe, it will be almost impossible to remove it manually. Therefore, it is cut down with a hammer and a long chisel.
A new one is installed in place of the cut-out gasket. The optimal choice would be a gasket from BOSAL, which is the official supplier of parts for Renault Logan exhaust systems (catalog number - 256–056, cost - from 400 rubles).
After installing the gasket, a pipe is installed on it, the previously unscrewed bolts by 10 are screwed into their regular places.
Going to the store for a new device for the Renault Logan car, you should know: this part is not sold anywhere in full. That is, the car owner will not be able to purchase the main muffler, resonator and intake pipe in one set. These parts will have to be purchased separately. It is better if the car owner opts for BOSAL products. Another good option would be ATIHO spare parts. In terms of cost, the products of these companies are almost the same:
the intake pipe costs 1,500 rubles;
main muffler - 2,000 rubles;
resonator - 1800 rubles.
Before starting work, you should decide on the necessary tools and consumables. Here's what we need:
new "Glushak" for "Logan";
liquid WD40;
socket heads for 10 and 16 with a ratchet wrench;
flashlight.
The machine is installed on an inspection pit or overpass.
The front of the muffler hangs on a rubber strap. It is processed with WD40 fluid.
After 15 minutes, the attachment pin of the device is manually removed from the rubber clamp.
Two nuts for 10 located at the junction of pipes with a gasket are unscrewed.
After that, the wire at the exhaust gas control sensor is manually disconnected.
In the back, near the resonator, there is a second sensor - a lambda probe. Its wire is also manually disconnected.
Next to the lambda probe wire is another rubber fixing clamp, which is also treated with WD40 fluid.
After 15 minutes, the rear of the mechanism is removed from the clamp.
This part rests on the crossbeam under the bottom of the machine. The beam interferes with the removal of the structure, so it must be unscrewed using the socket head 16.
After unscrewing the beam, the mechanism is completely removed from under the bottom of the car and replaced with a new one. After that, all fasteners are assembled in the reverse order.
So, even a novice car enthusiast can handle replacing the muffler with Renault Logan. All that is required is a pair of socket wrenches and the skill of working with them. Minor difficulties can arise with rusted bolts and tight clamps, but they can be successfully solved with the help of WD40 fluid, which is sold in every spare parts store.
Cars of the "Logan" family appeared on the domestic market in 2004 and quickly won the love of drivers. They are easy to maintain and unpretentious in operation. In addition, the Renault owner can carry out most of the repair work on his own. This also applies to issues of removal, repair and replacement of the muffler. Thin-walled mufflers cannot withstand many years of operation in winter-summer mode, and therefore the owner periodically has to carry out a number of works to restore the functions of the exhaust system.
The structure of the exhaust system on Renault Logan cars is exactly the same as on any other economy class vehicles. All components of the system are designed to remove exhaust gases from the exhaust manifold and reduce their noise during the exhaust process.
At the same time, the muffler quickly corrodes and depressurizes, because it is precisely on it that the main effect of the pulsation of gases and hot streams falls. The driver must be able to determine the performance of the "glushak", since the safety of driving a car depends on it. Determining a muffler malfunction is very simple - even a person who just yesterday got behind the wheel of a car can cope with this task.
First of all, it is recommended to drive Renault Logan onto a viewing pit or overpass, or use a lift. Of course, if there is neither one nor the other, you can just put the car on a jack. The main thing is to ensure yourself the convenience and safety when inspecting the muffler:
Examine pipes carefully for corrosion, holes, cracks, dark spots or dents.
Inspect butt joints for gas leaks.
Stagger the muffler by hand - it should not move away from its axis too much.
Check the reliability of all fasteners - bolts, nuts, brackets and rubber hangers.
If there is no visible damage to the pipes, then the muffler is in working order. A loud roar in the exhaust system and unpleasant odors in the passenger compartment are considered the first signs of a malfunction that the driver should look out for. The exhaust gases are colorless and odorless, however, due to depressurization of the muffler, they acquire a specific aroma that a person can smell.
Before repairing, you must make sure that it is appropriate. Sometimes drivers try to save completely rotten mufflers, when, like welding of large locations of burnout or corrosion, they are not able to restore the pipe's performance.
Most often, due to driving on uneven roads, the bracket fails - the muffler mount ... The pipe loses its position under the bottom, starts knocking on the body. Accordingly, the bracket must be welded back. In this case, it is necessary to observe the same dimensions and welding places as before, because the performance of the muffler will also depend on how correctly the bracket is welded.
However, not all drivers are experienced with a welding machine. Therefore, in a garage environment, it is easier to repair the bracket in a different way. Regardless of whether the mount has completely flown off or any of its element has fallen off, you can cut out the remains of the old bracket with a grinder and put an iron clamp in its place. It will perfectly perform the functions of the previous fastening, while it will cost several times cheaper than welding. However, it will be necessary to periodically check the condition of the clamp in order to timely change it to a new one.
It (the bracket) could simply be welded on or simply put on an iron clamp (20 rubles - a simple screw clamp) - they did this several times ... The problem disappeared ...

On Renault Logan cars, one of the vulnerabilities of the exhaust system is considered to be the gasket between the exhaust manifold and the intake pipe. If, while driving, the driver hears extraneous creaks, and there is a burning smell in the cabin, then, most likely, the problem lies precisely in the burnout of the gasket. In such a situation, it is urgent to replace it. Issue price: for self-repair up to 500 rubles., In a car service 2500-3000 rubles. The conclusion is obvious.
It is recommended to immediately start replacing this element:
Drive the car to the inspection pit.
Clean the junction between the collector and the pipe from dirt - it will be easier to work this way.
Unscrew the two nuts 10, which secure the two elements of the exhaust system to each other.
Lay the intake pipe to the side.
Remove the burnt gasket from the manifold pipe, wipe the joints with a clean cloth.
Then put a new gasket on the manifold hole and connect the intake pipe to it with two bolts.
Tighten the nuts all the way, but do not pinch them, otherwise you can break the thread and squeeze out a new gasket.
The muffler replacement procedure should be straightforward. The only important nuance is the choice of a new high-quality muffler. In order for a new product to serve for a long time, you need to know in advance about the selection criteria for "glushak" and their cost:
the Italian manufacturer Atiho offers simple and affordable mufflers made of ordinary steel. They will not serve for very long, but they are inexpensive - from 2 to 3 thousand rubles. assembled;
Miles mufflers are slightly more expensive - up to 3.5 thousand rubles, however, their service life will reach 6-7 years, since they are made of steel with an aluminum coating;
original Renault products are the most expensive - up to 8 thousand rubles, as they are made of stainless steel and therefore will serve for at least 10 years.
The criteria for selecting a muffler for a Renault car rest only on the financial capabilities of the owner: the more money, the better quality product you can buy.
To replace the muffler as quickly as possible, you need to prepare a simple set of tools in advance. The set includes two open-end wrenches for 10 and a flat screwdriver with a thin blade. You will need the wrenches to unscrew the nuts, and a screwdriver can come in handy if it is difficult to remove the muffler from the rubber bands with your hands.

After you have prepared access to the underbody of the car, you can start working.
Any work with the elements of the exhaust system is carried out only after the pipes and engine have completely cooled down.
It is recommended to adhere to the following rules to safely remove the muffler:
Remove the four bolts holding the muffler pants to the exhaust manifold.
After that, disconnect the oxygen sensor connector - you can remove it to the side so as not to interfere.
Remove rubber mountings along the entire length of the pipes. Then carefully lower the muffler down and pull it out from under the car.
That is all the work that will need to be done in order to remove the muffler from the Renault.
It is best to ensure that all rubber mountings are in good working order before installing the muffler. That is, they should not be stretched, have cracks or grooves. Otherwise, you need to immediately replace the rubber bands with new ones, because the reliability of the muffler fixation will depend on their condition.
The installation of the exhaust pipes is carried out in the reverse order:
First, the muffler is pulled under the car body.
After that, rubber bands are suspended on special hooks, and the muffler itself clings to the rubber bands.
The oxygen sensor connector is connected to the manifold.
After that, you can screw on the new bolts connecting the muffler and the manifold.
The bolts must be changed every time the pipes are replaced, since they quickly stick to the metal during long-term operation.
Repairing muffler elements and replacing them are procedures that do not require special knowledge and skills. However, following simple recommendations will significantly save on service station services.
This video will help in the following cases:
-increased exhaust noise (associated with damage to the tightness of the pipe and the breakthrough of exhaust gases)
-any welding work on the exhaust pipe
- contamination or damage to the catalyst (which can lead to a loss of power, gas breakthrough through the seals and oil seals of the internal combustion engine oil system)
- for any work related to the removal of the stretcher
To replace the muffler with Renault Logan, you will need a head for 8,10,16 as well as grease for rubber mounts, a lambda probe remover. In time, this procedure will take 20 minutes. Difficulties can arise when unscrewing the receiving pipe from the exhaust manifold, the threaded parts should be processed before starting work. It is also important to pay attention to the pressure springs on the mounting bolts of the intake pipe, most often they have to be changed or placed under them washers to seal the connection.
The average cost in a car service is 1500 rubles.
