Two brothers exhaust

[mehranir]

Hi everyone,
I just bought a 2009 fz6 and I am so happy:Flash: I have been thinking about getting the M2 Two Brothers slip ons; however, what is stopping and worring me is this back firing or missfiring issues that is talked about! Is it really that important to install a fuel managent system in order to have a smooth and good experience with the slip ons or can one get away with it?

I actually don't mind a little popping. Makes me laugh. When i had my FZ6, the dyno and PCIII with the Leo's installed was a sweet combo. However, when it was just the Leo's it still ran fine (with a little popping). The PCIII when dynoed makes everything a lot smoother. BTW, am now running the Two Bro's on the FZ1 with no PCIII and it runs like a cheetah!:rockon:

It will run just fine and I think you will be more than happy with the exhaust note. Yes, there may be more audible pops on decel, but nothing that is obnoxious or annoying.

Just be advised, your bike will be a LOT louder with these pipes. May want to invest in a nice set of ear plugs
