05 CRF450R WB Carbon Pro Exhaust

Recommended Posts

I did a search & was unable to find any info. I just got this exhaust & would like to get any input. My bike is stock no engine mods. Any body here in SJ,CA running it & what jets sizes being run. Just so I can get a starting point. I was told a couple of sizes up from stock? On the pilot & main.

I've been told It's the best exhaust for MX on this bike. It adds power every where. Thanks in advance.

It is probably made to go with the stock jetting. Why don't you put it on and try to feel if it needs a change?

I think you have to go up on the main, but I am not sure. Call White Bros, or check their web site.

Id run it stock first. Pipes dont make that big of a difference. The stock pipe is pretty dog gone good.

Bring one size larger for the main, but I doubt you'll notice much. If it noses over on the top end, it may be a tad lean on the main. Other than that...yada yada yada..
