Test Pipe

[drftfan]

For anyone running an SR20DET I highly recommend a 3 inch test pipe. Got mine put on the other day and it has made a big difference in acceleration. Also I am boosting as high as 8 psi due to better flow. The only draw back at all is the car is louder at WOT.

what size down pipe and exhaust you have?

I am running the greddy 3 inch downpipe and I had the high flow catco 3 inch cat to the Apexi GT spec exhaust which is almost 3.75 inches. So basicly the cat was shot so out it came. :evil:

got a 3" test pipe and 3" downpipe, now if I could only sell my greddy system to upgrade to a 3" catback, im still waiting

I definatley recommend any of the Apexi exhausts. I have had the N1 and I am currently running the GT. I only had to get rid of the N1 because a tow truck tore it up too bad on the muffler.
