Has anyone here put a 2007 1000rr on the dyno with a two bros exhaust?
What kind of gains did you receive?

 

If your just putting on the pipe you won't get all that much. But if you add the Two Brothers Juice Box, K&Ns or a BMC air filter along with Brisk spark plugs, it will be a nice little gain. I won't say what I gained cause of too many variables and it just opens up a can of worms on here, but she's a hell of a lot stronger now!

 

Yeah, I've noticed that most slip-ons don't offer much even if it is an Akrapovic, Arata, etc.....The only slip-on I've read about offering a substantial amount of gain is the Sato...which is like 8-10 hp.
