White Brothers E2

[400exrider2005]

Iv been thinking about noise levels and ive decided that the HMF is going to casue to many problems where i ride and i was wondering if anyone has the Dyno results for the E2 on a 400ex. I could also use some opinions about it. Any insite would be great thanks.

I have 1 on my 450r and love it very nice fit and the quality is second to none.The end cap comes off quick and you can install the spark arrestor and quite core in seconds.

As far as power there was an increase and I like it alot. You cant go wrong with the pipe IMO

Sorry no experience with the 400ex I have seen a guy with 1 on his ex at a local race and he liked it as well. think he blew a 93db with quite core and spark arrestor.

GL in your decision
