• 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.

exhaust noise.

reading all forums, i ordered a ecm from 3800 performance, cold plugs from advance, 180 thermostat, making cold air fwi, havereally put on already zzp 21/2 downpipe with high flow cat. also modular 3.4 pully setup and the puller. the ecm and pully go on last, thats what i.m learning from all you guys, and i want to thank you all for the info. watch out for old gray haired guy in 98 gtp

Yeah you've got that down pretty good. I would've gone 3" on the DP, but other than that nice setup man.
