Opinions on FMF Q or Q2

[ATC350X 85]

I plan to do a little work to my 450R once I have the top and bottom end done. What is everyones opinion on the FmF Q pipes. Noise is an issue where i ride. For starters i wanna do the pipe and a UNI filter, maybe try to locate a HRC lid and eventually a cam. Any ideas on what jet sizes? Thanks

i found that those pipes dont create that much more power than stock.

If your looking for a quiet pipe that makes good power, check out the BUB Moto C-4. Ive never been a fan of FMF 4 stroke pipes. The dont seem to make much power.
