Hey guys im getting an hks hi power exhaust for my b16 ek hatch and was wondering what test pipe i should get. the exhaust piping is 55mm so what size test pipe should i get?

 

why dont u just buy a random technology direct bolt on hi-flow cat? im running one on my HKS HI-Power and it sounds good ... a test pipe is gonna add some raspyness to the exhaust

 

will an invidia test pipe fit?, im just not sure if the collector is 2 bolt or three bolt. the hks picture looks like its a 2 bolt flange and the test pipes all have 3 bolt flanges. should i ge a.2.5 or 2.25 in test pipe?

 

...you should get a HIGH FLOW CAT. no test pipe at all. dont do it. listen when someone tells you something don't just repeat the question.
one more time HIGH FLOW CAT. 70 bucks won't hurt environment or the sound you'll be making. high flow cat.

 

ok. what high flow cat should i get.

 

Maybe you missed this.
