Best Exhaust System for 4.0L wj?

I'd imagine it sounds the same weiether it's an xj or a wrangler or what have you. But I'm looking at getting an exhaust system that will give me a good tone with a fair amount of noise to it. What have y'all done?

Re: Best Exhaust System for 4.0L wj?

just how loud do you want it? I dont have any clips, but flowmasters always sound good.
Do you have a auto or a stick? It DOES matter. i have a xj 5spd and wa running a ultraflow bullet muffler from summit.....that sounded sick! however i moved it to a auto xj(same engine) and it was way too much.

It's a 4.0l automatic 2004 grand Cherokee. I was thinking magnaflow cat and flowmaster super 40 or regular 40 series. There's a lot out there I just don't know what I want!
