Thats a slick setup. I like the look of those but cant afford much right now... im thinking about pulling the "cat" out of my stock muffler and leave the baffles? Then have it welded back on (cost maybe $15 max to get welded back together) & most of the xchamber and poopoo setups are $30+ shipping (shipping quotes are $15+) and up.
Also just realized i forgot to mention im from nebraska; seen a couple other mb around the city but not many.
