A noisy exhaust pipe is a great bother. Even without considering the hidden consequences, the noise alone should make you deal with the issue. Imagine driving into your gated community at night and waking up all your neighbors; the noise may even get you a citation from your local association. Here are four things you can do to deal with the noise:
Plug Exhaust Leaks
A noisy tailpipe is one of the most common symptoms of an exhaust leak. This is a deep and rumbling noise that differs from the normal noise of an exhaust system. Note that you don't have to crash your car or drive over a bad road for the exhaust to experience a leak. Thermal expansion and contraction, which is due to the heat emanating from the engine, is enough to cause a leak after several years of engine use. This is why the leaks are common in old cars. Consult a mechanic to identify the source of the leak and plug it. Don't ignore this problem, because the exhaust gases are a danger to your health if they reach the passenger compartment.
Unplug Exhaust Blockages
For your exhaust system to function efficiently, it should be free from any form of restriction. The exhaust is like a breathing mechanism to your car; you don't function well if your nose is blocked, do you? Plugged catalytic converters, damaged pipes, or crushed pipes can all restrict airflow out of the exhaust system. Consult your mechanic to confirm the diagnosis and unplug the restriction. Note that noise isn't the only problem associated with plugged exhausts; you may also experience loss of power and reduced fuel efficiency.
Install a Resonator
If you don't like your exhaust's noise, but there is nothing wrong with the car, then try silencing it with a resonator. The resonator is a hollow cylindrical tube that you attach to your exhaust system's muffler. Once installed, the exhaust noises have to pass through the resonator before hitting the atmosphere. The resonating chamber produces sound waves that cancel out the noisy waves from the exhaust. This is how it manages to quiet the exhaust. Although a few cars come equipped with resonators, most people add them as aftermarket products.
The list above doesn't contain all the things you can do to mitigate exhaust noises. If you still don't know why your exhaust system is noisy, contact a mechanic, like those at Marathon -Sleepy Hollow, for a professional diagnosis. Don't forget that, some of the time, exhaust noises are accompanied by decreased fuel efficiency.

When it comes to auto repairs, I am lucky. A good friend of mine is very car savvy and is able to make the majority of the repairs that my car needs. However, recently he sprung a question on me that surprised me. He asked if I wanted him to install a new part or a quality used car part. I asked for his opinion and did some research online. I was surprised to find that there wasn't a lot of information out there about when you should and should not use used parts in your car. So that's how this website came to be. I decided to compile the information I learned, so that in the future, someone doesn't have to search all over to decide whether to have a new or used car placed in their car. Hope my website helps you to make your decision!
