I just finished welding new 1 7/8" (outside) tubing to my exhaust flanges at the heads. So now I have about 1ft of pipe from each head. The old stuff was 1 3/4" outside I think, so this is a bit of improvement, the bend is also less restrictive than stock. When taking off the old pipes I found that the pipe out of the cat was flattened in at the top which was causing alot of restriction as well. I've got alot more power now. It sounds very sweet past 3k and rapidly letting off the gas produces some nice poppling and backfiring. My friend Alan (the jeep owner) left in shame after he experienced a 4lo launch in the gravel. After I finish the exhaust I've got a turbo maf that I will adapt, and I will bore out the throttle body a bit too.

 

QUESTION: How close do the stock pipes come to the steering rack cause mine are within an inch of the rack boots. I know I have to make a heatshield for that part but it still seems to close.

 

Ooh got 5 feet of 4x2 steel today

thats awesome! Myt rx's duals does the same thing with the popping exactly after 3k. Sounds sweet. Sorry i cant answer your question though.
