Has anyone put 4" exaust w/head pipe and kept the kitty. If so where did it fit bacause it doesn't look like it will fit next to the transfer case/trans. in the stock location. Looks like it would fit just forward of the 4 bolt flange but is heat an issue? Sorry for all the questions.

I put my kat on after the down pipe about 1 1/2 feet. If you dont have the finger stick it will still throw codes at you- back pressure will still cause the EGR codes to light up. So I took my Kat off and put on the finger/blocker plate, runs better than ever. NO MORE SOOT, she's breathing better now.:ro)
