LOVE THEMMMM

OOOHHH MYYYY GOD! I just installed this exhaust with the cat delete on my 2011 R1 about a week ago and they sound AMAZING! The bike sounds like a beast. There is a huge difference in power as well or at least it feels like there is. Throttle response feels a lot smoother as well. I'm constantly catching people staring at the bike in admiration when I give it a few revs at a stop light. I've had numerous people pull up next to me and tell me it sounds "BAD A%#". If you are thinking of getting these exhaust take my word for it and GET THEM!!!!

Awesome Performance

I wasn't sure with M4 as they are not as mainstream as the major players, but their quality is equal to anything else out there. They also produce a supper deep sound and improved mid range performance. Very happy and impressed.

Amazing pipe

This pipe is much better then the stock pipe on my 2005 honda cbr1000rr. It's loud but not to loud I could easily do a multiple hour ride with this pipe without getting a headache. It has a nice deep tone all the time.

Q: For the cbr600rr does it come with just the muffler or does it come with the pipe that connects to the cat as well?

A: Bolt-on and slip-ons systems utilize the stock header assembly, but remove the stock canister's restrictions, for better sound and an increase in power.
