Both me and my friend bought the same exact muffler off ebay from the same seller. I have a 2003 civic ex automatic, and he has a 1996 cavy automatic, and his muffler is RIDICULOUSLY louder than mine. This is fine with me bc i wasnt really looking for a loud muffler and im happy with the sound, but it still boggles my mind on how his is so much louder when its the same exact thing on a similar car?

he has no other mods, and the same shop put the mufflers on

Since both of you have two different cars, the size of the resonator could be different which makes the sound different between both of your cars.

i guess that makes sense, its just weird though because his is the loudest muffler i have ever heard, and mine is decently quiet. I was thinking it might be something more than the resonator.

different engines can have a something to do

But engines of very similar size shouldnt have that much of a sound difference... I just dont get it

well, every car is different unless they were put on the same car. you can never expect the same sound out of a set up on a different car.

Different size engine, different size exhaust piping, different resonator/cat/manifold. All these would differentiate the sound.

dont forget the bends of the pipings on his vehicle compared to yours.

his car can even be pushing out more fumes and exhaust gases thus causing it to be "louder"
