Hmm
..that doesn't sound muffler related...but I guess if u want it to be loud go for a flowmaster 10.it shouldn't harm nor hurt you...also on the safe side...also id look at your o2 sensors for that idel issue

Renix have no parameters for back pressure.. I believe late jeeps do as taking the cat off should throw a cel.. it may lean out the mixture a little....

Right vehicles that have an o2 in the cat you rly can't cut them off BC of that sensor...but his problem sounds like something else. Maybe a cracked header ? Or f'd up manifold gasket?

it can't be a back pressure issue BC even at the headers and down pipe there is back pressure removing muffler and tail pipe or having a glass pack should not do that.

No I don't believe it will. Go to the website and see if your header fits your 96...if not I will take it for my 93 lol
