Secondary Cat Bypass Pipes Installed

You will definately hear a difference with the bypass pipes...it was quite noticable on my 3.2. Again, I feel the biggest difference before and after is the throttle response. On heel/toe downshifts, there was always a slight hesitation on the throttle blip, even with e-gas. The response is pretty instantaneous now; I wasn't imagining it, now that I have had some more seat time.

Exhaust note is a little louder/deeper at idle. Where it really sounds different is above 3600-3800 rpms; the mid range just opens up with an aggressive howl. I'll have to record some, as I have difficulty describing the sound. I spend a lot of time at the track and it is similar to the sound a GT3 makes when heavy on the throttle.
