I'm looking for a stock exhaust replacement for a 99 xj. I'm told the Walker quiet flow is anything but cuz everyone know what is a nice quiet one?

Omix-ada?

I run a Quite Flow on my '00.
Probably the wrong person to comment cause I don't really care.
But I think it is OK.

Good question OP. I'm looking for a quiet one that's seamless in 2 1/2".

Flowmaster 50 series.

DynoMax. That's what I've been running for quite awhile. 5+ yrs. Third cat back on the jeeps. There reasonable sound and pretty low bang for the buck. I always paint mine with 2000 Deg. black grill paint and they last a bit longer. Id say its pretty tame as far as sound.
