UXOC has a deal with a local muffler and exhaust shop to get a really good deal on exhaust systems for less than some of the ones available online.
We got cat-backs with 2.5" wide mandrel bent pipes, when I went in they didn't have the mufflers they were putting on the rest of the club so they gave me a new Hooker Aero Chamber muffler for the same price.
Looks good, sounds good but not too loud, and feels a bit more energetic.
