Update on the bike

How is the performance of the 2 bro's exhaust? I've heard rumors it robs power.

Based upon the YouTube dyno run, it is one of the very few that actually adds meaningful power (9 HP & 5.5 Ft-Lbs). I just couldn't bring myself to disrupt the CBs vintage design with a modern exhaust can, much less carbon fiber. But, for those after that look, it is a winner.

Yea that would be some substantial gains from just a bolt on muffler. Heck, that would be substantial gains from a complete system. I'd be more inclined to believe those numbers if I saw an independent dyno chart verifying that. That video didn't show anything. Basically it was a sound check. No one on this forum has been able to repeat those gains. We have a dyno results thread someplace. Plus 9 hp would put a CB1100 in the 96 hp category.

They showed the dyno run chart. But, I am not inclined to believe it.
