Look at the AFE high tuck. They make a 2.5 and a 3 inch version. It gives a nice deep tone. I've ran it on my 2dr 08 for bout a year or so now

 

It's is the same as the evolution I have. Only difference if the rock crawler exits out the back and the evo dumps before the rear axle

Do you have a mbrp off road setup? Thats what i had and after a road trip with my wife she hated my jeep. Switched it out with the dynomax super turbo with a slight bend in the pipe to make it fit. IMO the setup ive ever heard yet. Still has a deep idle, nice deep mellow tone in stop and go but totally shuts up when you cruise and at part throttle. Extremely happy. I can youtube a video if you like. Or look up my video channel. Courtsm3 on youtube. You can hear my jeep when i cross a couple logs. Turn it up!!

 

Sorry. Its actually under my buddies page. Nick Drader channel. Red JKU

 

PM me and i can make a video for you. Real world too.

Here. Dynomax Evo Catback - YouTube The Gibson and aFe were my other 2 favorites but I opted for the dynomax because of clearance. If you go aFe get the 2.5in unless you plan to go forced induction
