I like the sound of Banks exhaust but not so much the price at $300. Get yourself a good highflow muffler like a Magnaflow Flowmaster 40 and save atleast half the price of the banks setup... And ive heard of people banging up expensive exhaust setups while jeeping so another reason to go cheap and still get good sound ;D

It's still a 6-cylinder so you're not going to get them deep v8 growls like you might be anticipating. I have a Borla exhaust setup, and it sounds pretty deep and aggressive. Straight-pipping would probably be your most aggressive setup, but it's illegal in many states.

And when you go with a Flowmaster 40 be sure to go with a slightly larger tailpipe then stock as well about .25 bigger and you wont be disappointed ;D Ive heard the Banks in person and a Flowmaster 40 with a nice tip.

If you want deeper the 50 should do the trick.

CAI, TB spacer, Borla header, cut the cat out, flowmaster super 40. Love the sound of mine. Did have turn downs right after the muffler, but the resonation at highway speeds was horrid in the cab. Moved the outlet back closer to the stock location with a tip...sounds much better now. Quiet in the cab and quite throaty out back on accel. As good as your goin to get with a 6 cyl anyhow.

Don't let anyone else see you saying this. They'll rip you a new one.

But I'm all for a CAI and TB spacer and I like the sound and the little performance gain from it.

Definitely like my Borla. It's throaty and has a nice range when I drive. I think it's the perfect blend between that aggressive sound I'm looking for without going overboard and ricer like a cherry bomb. As far as a CAI and TB, my PO installed a K&N and TBS. You get a nice whistle like a turbo, but as far as performance you're not actually gaining anything. Don't spend or waste your money, especially because off-road they're terrible.

I agree with what other say and go cheap, especially if you offroad. I have a Cherry Bomb Extreme installed on mine and I have had many compliments on it, people say it sounds like a small V8. I think the muffler was only like 60 bucks and i had a local exhaust shop weld it on.

I personally love the sound of mine. I have straight pipe welded where my muffler was. Cheap and sounds great

The loudest most aggressive you can go with is to eliminate the muffler with a straight pipe followed by a glass pack muffler. I believe both aren't street legal.

I used to want a louder exhaust too......if I had the room, I'd run a big-ass muffler and run as quietly as possible. It'll get annoying to you and others around you.

my friend straight pipe'd his jeep.

It's loud, obnoxious and sounds similar to this:


I hate loud exhausts on a Jeep, or any off-road vehicle for that matter. Nothing will ruin your perfectly peaceful camping trip in the wilderness like waking up to some moron romping the throttle of a loud arse vehicle at 6am.
