I've got extractors down to cats, to resonators and H pipe, then to generic oval rear mufflers, all 2.25" pipe. Sounds very nice IMO, kinda loud outside the car. Inside it sounds pretty lumpy when you stand on the go pedal (read: not loud) with windows up. When just cruising around town or highway, sound is hardly noticable, if at all.
At the moment theres this gaping big hole where the exhaust mount was welded to that's decided it didn't like being there anymore. Damn it's loud, will be fixed soon!
