And Id love to throw a Y pipe on there, the only thing stopping me is the thought of having an old Cat in the middle of it all... I dont wanna spend an extra 200 bucks on the cat and turn the Y pipe into a 500 dollar project. How many of you have put a catback and a Y and just left the Converter on there?

 

Why not just leave it? It's 2.5in dia through the cat.

 

You don't know much about A32's do you?

They don't mind the stock cat there.

Get it for looks, but nothing more than anything.

Hell, I even have the stock cat on my VQ35 and it loves it just fine. Shoud've bought the y-pipe first and called it good.

 

i have stock cat on mine

 

everything below my car (exhaust) are stock.

 

the stock cat is by far better than any aftermarket piece. i have a carsound and its falling apart inside. i only bought it so i didnt have to mess with the old bolts.

 

Here is my set up.

Warpspeed Y Pipe --> OEM Cat --> Apexi WS Cat Back

 

Yea but they do get clogged up

 

you are soo right....stock cats on our cars are lovely

y-pipe>cat-back.........

Straight pipes yeild no gains unless you are using them to tune A/F Ratio on a dyno.
