I'm looking at the magnaflowmhigh glass pack for my 91 4.0 I was something that sounds good and doesn't early have drone. Not looking for anything crazy or flowmasters.
What muffler? And 3 cats?I have a complete custom Magnaflow exhaust on my YJ, and it sounds great. Its an 87 with a 4.2, but basically the same as yours.
The only thing i did different is i went with a 2.75" pipe front to back, to let it breathe easier.
On their website i belive the cat back kit is around 275ish, with your choice of muffler.
I went with the Magnaflow glasspack 16" long, 4" diameter. Gives a deeper lower tone than a cherry bomb or similar glass pack. And the nice thing about my Magnaflow system is, everything is stainless.What muffler? And 3 cats?
