919 CBR900 Exhaust Pics and Video

Just thought I'd post these for those interested in the CBR900 exhaust for the 919. I know it was specifically difficult finding a sound clip of something like this before I started the project.

Header - $90 local on ebay
Carbon fiber D&D muffler (no baffles) - $90 shipped on ebay (great find - new, but opened by someone who never used it)
Mounting bracket by local mechanic - $70 for an hour of labor
New gaskets - $30

I did the work myself with my brother-in-law (with the exception of the bracket). The header was a black one to begin with, but I sprayed it with a ceramic black paint for good measure.





And yes, I'd like to apologize and note that my bike was not properly warmed up. Shame on me.

Nice bike & nice job with the video too. Oliver Stone's got nothing on you.

Yes, yes. I know. I shake. I tried to be as steady as I could, but it was just a digital camera with no anti-shake feature. And yes, I've had it checked out by a specialist and there's nothing wrong with me.

What do you think it is that makes that sound? That was there with the stock pipes as well. I just assumed it was the engine itself.

Sounds just like mine with the bafflectomy. Yours is "stink free" though!

Hey, that's pretty original! A PCIII and a dyno run might help sqeeze some extra hp out of the new exhaust system.

Two for thinking outside the box. Sounds mean too.

Although I appreciate the comments, I can't take complete credit. Lots of members here had the 900rr exhaust idea well before I, and it was one such member that inspired me via this pic...

Thanks to support_six for the inspiration. I like it this way much more than the chrome/aluminum setups.

To be honest with you, I don't know. I'm not a super agressive rider as it is, and here lately I haven't been out on any twisties. Just mainly to work and back on straight hwy or city streets for two miles each direction. I've never heard of anyone with this setup complaining. It is, after all, the stock CBR900 header.

Yeah! What he said


When I get mine done, I'll tip her over and find out.

I dragged the can & the peg on the asphalt at VIR only because I wasn't hanging off the seat enough.
So if you ride properly, no.
