Does changing muffler increase sound?
Installing an exhaust tip with a wider or narrower diameter than the tailpipe can change the exhaust note. A wider exhaust tip can increase the throatiness of the sounds made by the engine and exhaust. In contrast, a narrower exhaust tip can make the vehicle sound raspier.
How does a muffler quiet exhaust noise?
Mufflers silence sound waves by converting the sound wave energy into heat by passing the exhaust gas and it’s accompanying wave pattern, through perforated tubes and tuning chambers. Passing into perforations and reflectors within the chamber forces the sound waves to dissipate their energy.
Which exhaust tip will change the sound?
Exhaust tips, since they are literally at the tailend of the exhaust system, will make a car have a more powerful sound. But a normal tip typically will have a small effect on the exhaust sound. A larger tip will give the engine a stronger, hearty sound, while a small tip will produce a raspy sound.
Do rolled exhaust tips change sound?
The shape and width of the exhaust tip can slightly change the sound to be either more throaty (larger tips) or raspy (smaller tips). Double-walled muffler tips tend to add a full-bodied sound. On their own, though, muffler tips will have a minimal effect on exhaust sound.
Do muffler silencers affect performance?
Looks like on low power naturally aspirated cars, silencers don’t affect much, if anything at all.
Can you pack a muffler with steel wool?
Yep, it’s been done. My neighbor used to do it many years ago. It was a good trick to pack the bored out mufflers with steel wool to get to quiet noisy exhausts. But the steel wool would eventually either burn up or rust away (which was the goal to get back to a loud unrestricted exhaust).

It’s all about quality control, JASMA exhausts have to meet a 96db limit, amongst other things. I’m with Rezz, the 96db rating will be on a stock car with only the exhaust changed on it though. Stick on a big turbo with a back cut exhaust turbine and say goodbye to your 96db car.
