Facts:

Question:
What is the largest diameter exhaust pipe I can run on this gas engine w/out hurting performance & keeping proper back pressure?
Thanks,

i think with a setup like that, 2.25-2.5" dual exhaust or 3" single
I was running dual 2.5 and witha similiar set up, and it ran great

I had a CJ-7 with the same thing, dual 2.5 flowmasters and cats. Had great responce(sounded mean also).

Mine's 2.5" into 3.5" single with a 94-97 powerstroke muffler. Seems to work fine. And the 3.5" turn down at the back looks pretty mean. No lack of bottom end, in fact, about all it has is bottom end with the stock cam.
