Jeep Grand Cherokee (WJ) 4.0 L - New 3" Straight Pipe Exhaust 

Evan Griffith no, because there is no O2 sensor there is no way for the engine to detect that the cat is gone.

i think only on newer xjs there are O2 sensors behind the cat.

Only asking cause mines cut off at the same spot and I’m having horrible hesitation due to no back pressure and I got a check engine light from the 02s

No it was the cat jeep grand cherokees of that year don't have resonators, I have the same car lol

But it was got $100 for it in scrap 😂
