Am I going to be ok for exhaust with a 8-9 psi .60/.48 setup? I know 2 1/4 straight pipe is still pretty restrictive... I will probly upgrade in the future to 2.5 or 3, but I am out of cash.

 

Thats what I run. But no cat.

 

i will be running the same temporarily until i have money for 2.5"

 

.25" isn't going to make a world of difference, but yeah, the bigger the better. You'll be fine.

w00t for a 3.75" exhaust!

 

Well im using a Dynomax exhuast, and midpipe, i think that the midpipe is 2 3/8, and the muffler is 2 1/4, but it has the flanges that get to stock size, so say like 2 inch or something, would that be too restrictive?

 

Mine is, but it still has those small flanges?

 

i had stock 2 1/4" exhaust and went 2 1/2" mandrel bent no cat on both exhaust. the 2 1/2" gave me 12 more horses at the dyno when i went to retune on the first dyno run before
the aditional tunning. and i noticed the turbo spooled a bit faster.
