Re: SRT-6 vs. Boxster S
I doubt the rear cat delete produced any gains. To me it feels the car pulls a little harder on top of the rev range, but I have no proof of it. I did read some thread about some guys in Florida did a resonator and rear cat delete before and after that suppossedly made an extra 12 hp on the dyno. To be honest with the only difference is a little more exhaust note. I did it in anticipation of my next exhaust mod, I only have so much available cash to throw at my car, so I am doing it in stages. Unlike some I am a working stiff.
