The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.
High Flow Converter...Glasspack for a resonator...quiet thrush style muffler...probably a couple hundred bucks in exhaust...sounds way better...gain a few ponies...and a few MPG's to boot.
I have an 01 3.1 GP with the 2.5 inch GMPP exhaust system which is a magnaflow dual system for the 3.8 GP's. I bought a driver's side rear exhaust hanger for the GT/GTP. I also eliminated the u bend right after the converter. The system consists of 2 stainless steel magnaflow mufflers and a stainless magnaflow resonator. After the install, I found the sound a bit too loud for my taste at low RPM's and on the high way so I added another 12 inch resonator right behind the magnaflow resonator and now the sound is perfect. I can't say that the mileage is any better (it was real good before, especially around town) but it definitely has more power. The only problem is/was is that this system is expensive-everything was about $500 but i love the sound now and it looks great with the duals.
I bought mine from Gmpartsdirect.com about 2 years ago and up until very recently it was still available for $450 which was a steal. I just checked for you and GM no longer sells it-bummer! The part number is still listed though.
alright thanks ive been on there but cant buy it from them ive heard of some other places but never found a place order it from..guess im just gonna have to make my own
