2 Bros dual carbon slip on. Best looking exhaust I've seen and has the perfect volume......not too loud when you want it quiet, but screams above 10K rpm.
So many aftermarket exhausts look like a big dildo hanging off the rear of the bike......others look like a complete afterthought hanging back there. The 2 bros. looks like the bike was designed around the exhaust instead of the exhaust being designed around the bike.
If I wanted something louder, the pic's I see of the hotbodies exhaust for the 06's looks sick but I haven't seen one in person.
