White Bros E2 exhaust

anyone have a White Bros E2 exhaust? I was wondering about sound and if there is any power loss? Vance and Hines just purchased the co. so I read, I wonder if they will stand behind WB pre-existing parts??

Thanks Steve

When running the quiet core on an E2 there is significant power loss. My buddy tested over 98db with his E2 on his WR.

You know, it's driving me nut's!!!!:thumbsup: I need to make my yz more quiet, but don't want to loose power (that;s why I bought a 450:thumbsup: ) But it looks like a fmf q4 is the answer for quiet and s/a. thanks

I have the E2 on my 426 as I like to ride enduros too and it has been fine. I had to re-jet the bike a bit and yes there was a slight "snap" loss but all is good. I like how once you go to the track and take the silencer out boom it's all good for the track too. At my last race I came in at 96db. Just my 2 cents.

I recently bought an E2 for my 06 450 and it has been a great pipe, with or without the spark arrestor, it looks awesome too.. its actually for sale right now, im upgrading to a full exhaust maybe a DRD i dunno yet.. anyone thats interested, pm me
