just wondering which test pipe do i use? i have a b-series with a apexi ws2 exhaust. or do i have to get it custom made at an exhaust shop. will the header and exhaust line up or will i have to bend the pipe? thanks in advance.

 

the exhaust place shuold be able to tell you

 

get it done at an exhaust place.. much cheaper and you wont get *** raped by a brand name.
