ANyone know the stock sound decibel? I have a pro moto billet end cap with the spark arrestor in and without the sound dampning plug. I have a race on sunday and there is a strict 99 decibel limit. Any help?

Yeah, I think my '06 is one of the loudest bikes I have heard/ridden. I ordered an Akrapovic evolution system the other day, it should be here on Thursday. They are supposed to quiet the '06 down a little, without robbing any power. I hope so, it is starting to give me an ear ache.

It's loud, but not that loud. I think that it is closer to 100db.

If you order a db dawg insert now, you could have it in time for sunday... If you fail the sound test the insert will install in seconds. You will pass with that in there. Its only $39

Quiet is Cool Products ( www.quietiscool.com ) has some great products that might be able to quiet it down. I use their stuff in my 400 and 426 with great success.
