CA sound regulation White Bros E-series

5 posts in this topic

I have YZ 426 with a White Bros E-series muffler. I also have the useless quiet baffle insert thing. How many washers, or plates do I need to run to get it at 96db. I run 12 now for tracks.

Thanks

dude,

I run the wb eseries on my 00 426 and there is no combo that will bring it down to 96. (at least not with mine) some use 4-5 disks but lose all low end. I know where you can get a used FMF Q for like $90 plus shipping if you want to quiet the beast down.

I have the same bike and I had to go to 4 disks and it passed. I ran like hell but it was better than packing up or paying the fine @ Holister.
