Stage 3 guys...What exhaust are you using? Who makes a 3" exhaust with race cat?
#7
I'm using the APR cat ...
but still with my old Neuspeed/Borla exhaust, which I believe is only 2.25". That will probably be the last thing I upgrade, sine I'm currently getting the power numbers I expect (wondering how much more I'll really get from a 3" setup). I'll just have it cut at the cat and run 3" from there (the APR cat goes from the 3" downpipe to a 2.5" out).
