    I just did a set of true duals today. No cats, but I ran them side by side, all the way back and over the axle to, um, no muffler . No pics yet since my camera took a dump on me.

    It sounds seeexy, but if I start to go up a hill the intensity is wicked. What I plan on doing is putting the ole cat's heat shields over the bullets (camo for inspection), and putting 2 more in the back as "mufflers." I know it sounds odd, but last year I passed emissions test w/o cats and a bottle of RXP addidtive, but failed the "visual" portion of the inspection since I have no cat(s). Maybe this way I can give it a shot at inspection lol
