Exhaust Help!
 

Got a 98 GSR, sotck headers and cat with Apexi WSII catback exhuast, looking to use 2.5" T1R test pipe and hytech replica headers, i was wondering if anyone would know of any fitment issues i may encounter while utlizing such components?:confused: Any advice is greatly appreciated.

hytech and replica headers eliminate the cat. if you wanna run that header and the test pipe, you'll have to shorten your B pipe. why do you wanna run a test pipe in the first place? you do realize that it's illegal, right?
