Basically, it takes all the noise from the engine’s exhaust gases and dramatically reduces it. It doesn't completely eliminate it, obviously, but it’s the main thing that keeps your car from sounding like a race car. It does this using a series of chambers and tubes inside that bounce the sound waves around and cancel a lot of them out. It also allows the exhaust gases to exit the vehicle properly. It’s the very last part of your exhaust system, right at the tailpipe. Think of it as the final gatekeeper before the exhaust goes out into the air. All the harmful gases, after being partly cleaned up by the catalytic converter, flow through this. It's a pretty simple component, but crucial. Well, besides just not annoying the neighbors, a functioning rear silencer is important for a few reasons. A failing or damaged one will make your car really loud – you’ll notice if it’s gone bad pretty quickly. But more than that, leaks in the silencer can allow exhaust fumes – which, as I said, aren’t great to breathe – into the cabin of the car. It also affects backpressure, which can mess with how efficiently your engine runs, potentially lowering your gas mileage. You can find replacements easily enough; we often have a good selection at Fixparts Online. A new silencer will bring your exhaust system back to working properly and keep things running smoothly.
