Lookin for the best pipe for my 450r. I cant get a pipe that is over 96 db's due to trail rules. Can only afford a slip-on for now. What pipe do you think would be best. Some that i have been lookin into are the trs yoshimura, white bros e-2, fmf factory 4, hmf, dr.d.

 

I haven't seen any quiet pipe shootouts for the 450R yet, but the one for the yfz450 showed the Dr. D getting the most gain for a "quiet" pipe.

 

I know that some person is having a shoot out at exriders . com but i couldn't find it today... If i remember right Rossier was really good
