3in Test pipes? (2007 coupe)
I just recently installed a 3in dual exit exhaust from Z1 motorsports and don't get me wrong I LOVE the exhaust I put on but i am wondering if there's any 3in Test pipes on the market that will fit the exhaust that's installed
The stock header collector is only like 1.75", aftermarkets are like 2". No need to run massive test pipes.
Normally you don't go to 3" pipe until the y-pipe collector when running a single pipe exhaust.
