Your stock piping is 2.25". The choice of size that you want is up to you.

So I can put a 3" down pipe on even though its 2.25"?

So what would you recommend cat? No cat? 2.5" or 3"? I don't know a lot about this stuff

I have headers and a downpipe for 150+shipping

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?

No.
It bottle necks.
Sell the downpipe and buy the pacesetters like I told you in your other thread.

Who's pacesetter? He'll I can't remember who texts maybe I need to put names with the messages lol

I was talking to that Mike guy above my post.

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.

Who is Pacesetter? You know that reoccurring nightmare you have? Pacesetter is kinda like that. He builds you up just to destroy you, then you wake up and realize its just a dream.
