WB e-series and Cal 96db law

5 posts in this topic

I have a friend with a 00 650r that is planning to go riding with me in 2 weeks and has White Bros e-series pipe. The place we are going does check sound and he has never had the bike checked. We cannot find a quite core for it , it is on backorder everywhere ,WB, parts unlimited , everywhere. Has anyone had it pass sound, if so how many disk did you have in it? We are looking for any ideas. This was supposed to be a three day camping trip and I don't want to see him not go. He bought the bike used and did not get the stock pipe for it and I don't know anyone that has one to loan him.

Thanks

Bigman

Here is a reply I got from an individual on the yahoo group.

"I have a white bros E-series and header and its a great pipe. It will also pass the sound test 95.999999999999 decibels with 12 shims."

I have one on my L, and I am running it with 6 disc. I would venture to say that it would pass the 96 db law. It really is kind of quiet. And with 6 disc, the motor will produce more low end power where you need it.

I have got an e series on my 01 and have measured it at 98db. I put in the quiet core and it didn't seem to make much difference. The guys at White Brothers told me that you may have to go down to 6 disks. I pulled a few disks out and didn't like the power loss although I achieved the 96 nirvana. I ride open desert and they don't check the sound too much so I will leave it wide open for now. :)
