Can I Use A Fmf Head Pipe With My Stock Muffler? I Don't Want A Full System Because My Bike Is Quiet And Sounds Good. I Have A

Gyt-r Insert In The Stock Muffler. Fmf Says It Increases Power And Quiets The Bike By 2db. Does This Sound Right?

Thanks For The Help

As for the increasing horsepower yet quieting it -- I truly find that hard to believe, given that quieting it would restrict it and thus decrease horsepower.

...Although it could be something "gimmicky" like increasing top end a smidge but decreasing everywhere else...
