im just looking for adding a muffler to my car, ill end up doing it right before inspection cause i love this no muffler beastly sound...but i was browsing magnaflow and i was curious if the over all roundness of the muffler will make a difference to the sound because i noticed they have 5" 6" and 7" round mufflers...and i planned on asking magnaflow but does anybody know when they say for ex. 2.5" or 3" in/out are they talking about inlet diameter or outlet diameter
