Hey guys can anyone tell me what the decible level is on a XR650R uncorked with stock pipe? I want to buy an aftermarket pipe but dont what it to be any louder than it is now. I want to keep the riding areas open! Thanks guys!

Is the tip opened up on the stock pipe with a 2" hole saw... :)
The bike probly won't run well without the pipe opened up and rest of it uncorked.......
I would think the stock pipe opened up as stated above would probly not pass a db test...Not sure though........ :)

I don't have a db meter but I can say it is still very tolerable. Mine is a little louder than stock, but nowhere near as loud as my YZ426 with a Thunder alley full pipe. :)
I would think you could still pass the db test at most parks pretty easily.

Dirt Bike magazine did a article on sound testing in the April issue. Though they omitted xr650r info. they gave a link to a California state gov. web site that had the HRC tip blowing a 97db. I`m using the HRC tip with B.D Baja Baffle which keeps things pretty quiet without giving up much performance.
