Hey guys I'm a noob and need help, I have a 2000 gtp and I want a down pipe for it but I don't know the size I need. I looked everywhere so can someone help me?
 




Is the stock piping 2.25? I thought it was 2.5" was for gtp and 2.25" was for the 3100 SE.. The 2.5" glasspack just slid onto my catback and was able to slide inside my cat...
 
I would only get a cat if you have emissions. Running careless will set a code for the downstream o2 sensor. That code can be tuned out.
 
Hey I know I posted this a while ago I bought my down pipe it's 3" my friend is trying to say I need a converter for 3" to 2.25" do I need one or no?

It bottle necks.

Sell the downpipe and buy the pacesetters like I told you in your other thread.

isnt the stock cat good to 300 hp?if so wont be a bottle neck untill he reaches that amount of hp.
op: if you do keep the 3'' downpipe, then yes you need 3'' to 2.25' reducer so it will fit t your cat.
