Sounds clip of my E55...
Which ones are the resonators? I know there are in order - 2 cats, a long straight muffler (I replaced this with dual straight pipes and the sound is a little louder and better) and a muffler looking thing just behind the rear bumper.
Thanks, mp
Instead of a straight pipe, some folkes do a Y-Pipe.

Straight Pipe VS H-Pipe VS Y-Pipe VS X-Pipe
I like straight pipes. Our cars already make enough power, it's the sound I want!
