Thread: Adding a CAT back exaust system

im thinking of going to a local shop here in mass that is very popular and does good custom workwork and bends all their won pipes to make you a custom system to add at CAT back to my GTP to give it a better sound i was wondering if anyway had experience w/ a system like this not your typical one that you would buy

Would it make it sound better? I don't think so. That's just me. These cars don't have great sounding exhaust. But I dunno u may like it

Maybe its just me but, i actually like the way these cars sound.

I have SLP catback, its overpriced but, I like it. If your gonna build your own, look up sound clips on youtube, there are plenty there. Alot of guys on here fab up their own catbacks.

i had the slp on my old gp... i liked it but it tended to get a lil raspy in the upper rpm range. I think the GM Performance Parts catback is really nice or a ZZP 3 inch Catback... just get it with their "whisper" resonator.

Or...

YouTube - GTP Exhaust 2

The 2nd one was about 40K after the first video...mufflers/resonator were broken in and exhaust leaks fixed I think...
