A corrugated pipe or vibration compensator is a flexible element that acts as a flexible connection in the exhaust system.
Externally, it resembles an elastic tube with a multilayer mesh metal weave and acts as an intermediate link between the exhaust pipe and the muffler downpipe. The corrugated pipe is often used to replace a section of a burnt-out exhaust pipe.
Due to its design, the corrugation not only compensates for the vibration that accompanies engine operation, but also dampens the vibrations that occur when starting the car.
The corrugated pipe is an elastic tube with a metal weave in the form of a multilayer mesh.
Corrugated tubing can come in a variety of designs. It can consist of two or three layers, and have a single or double reinforced braid. In any case, it is made of durable stainless steel.
Despite its strength, the corrugated pipe is quite sensitive to mechanical damage and is subject to wear.
Burnout is a common problem with all muffler components. A burnt-out part no longer performs its intended function, leading to uncomfortable driving and can even pose a danger to the driver.
Unfortunately, not a single corrugation It cannot be overhauled, so there are only two options for eliminating a burnt-out element:
Change together with the pipe.
Change separately, leave the pipe as is.
Cutting out worn corrugation
Once the new part has been purchased, we can get to work. Replacing the muffler corrugation isn't a particularly difficult job, but it can take several hours for a non-expert. Remove the exhaust system section. Using an angle grinder with a cutting disc, cut off the damaged section as close to the original weld as possible.
After this, we put the pipe back in place and insert the new corrugated pipe. This is necessary (especially if you're doing the job for the first time) to ensure the new muffler corrugated pipe fits correctly, as this would place additional stress on it and reduce its service life.
Welding works
You most likely have a standard inverter-type welder. Ideally, you should use a semiautomatic welder with a wire feed for this procedure. However, in the latter case, you probably wouldn't even consider calling a service center to replace the corrugated pipe. However, if you or your friends don't have a semiautomatic welder, you'll have to choose this option.
You can replace a corrugated pipe at almost any auto repair shop. The cost varies from 2,000 to 5,000 rubles, depending on the car make and type of exhaust system. The process takes no more than half an hour. Professionals can also repair it, but the best option is to replace it with a new one.
