If you're looking to do it yourself, you can buy a complete exhaust system, or buy the components separately. I went with the Dynomax catback from Summit Racing, which has the tailpipe coming out almost horizontal, and cocked slightly to the passenger side (if you have, or are planning to use shackles, you will have to modify it). I think I paid right around 135 shipped last year, and got a $50 credit on my future purchases to boot. Not familiar with Wranglers, but there are a variety of tailpipe setups available if you shop around, some of which you can buy separately, as opposed to a full catback setup. I was going to piece together a system this way (didn't think the Turbo muffler would suit my tastes, as I'd had one on my old Sonoma, but it actually sounds good, IMO), but the deal they had going was too good to pass up. Hope that helps.
