Chasing 3.5" To 4" Exhaust Cat Back > Gtr R32

[paulyp]

Hi all,

Just after a 3.5 or 4" cat-back exhaust for my GTR R32.

Need to upgrade from my 3"-3.5" Apexi one as I am chasing 400kw.

Thanks

External gate? Or internal either way run a 2" exhaust from your gate, add a cat and muffler? Legal, quite and 5" of exhaust all up, oh and a lot cheaper too [emoji106]

I'm running mine just long enough for the cat and muffler and dump it

Hi, I already have 3" dump pipes with a Hks front pipe so it will be internal gate. Mainly just after exhaust post cat. Where did you get your system from? Sounds good.

Got it made at a good exhaust shop on the Gold Coast. Main reason I went this way was price of course and 5" is a lot to fit under your car, I thought some of the dump/front pipes were split anyway ?

Not sure how much you paid but I can tell you that most exhaust shops here in Sydney are expensive. Yeah some dumps and front pipes are split but my ones are all open (bellmouth)
