450R Exhaust 99db & Lower

[ravage3000]

Ok, a friend of mine and his brother got used 450R's (04 and 06) and needs a exhaust thats 99db and lower, and also needs it to be modified to 96db (quiet inserts, etc..) He has a computer and internet, he's just not bright enough to use it well hehe. Anyway, he gets parts at a very good price at a dealer and has it narrored down to these systems..

Pro Circuit - T-4 System
FMF - Factory 4
Yoshimura - RS-7 Comp / Pro
Yoshimura - TRC Comp / Pro
Akrapovic - Evolution Series
Two Brothers - M-7
Hindle - Full System
White Bros. - Carbon Pro / Aluminum Pro AMA Pro

He does a lot of trail riding, pits and service roads and plans on doing mx riding. If anyone have dyno charts and db rating that would be great ! Thank you.

I have a Dr. D slip-on with a quiet core insert. It says on thier website it is 96db. I was tested before the last race at 94db. Twice in a row. That is at 3750 RPMs.

ALso the FMF Q2.

Thanks for the reply ! but we don't get Dr.D products here (Parts Canada, Motovan, Kimpex...)

He doesn't want to get the FMF Q.

i know what your saying about the choices here in canada, :( i got the same ones, anyways i once tried a 04 with a yoshi trc, and it was very quiet with nice gains, i myslef am likely going to go with a dg x2 for my 06 or an yoshi rs-7 through parts canada, the dg might be too loud for his liking since its just an HMF with a different end cap

These would be my choices, in no particular order!

Yoshimura - RS-7 Comp / Pro
Yoshimura - TRC Comp / Pro
Akrapovic - Evolution Series
