Ight some i been doing some rides around with peoples and I happend to ride with this zx-10r with that bozbros pips that comes right out under right rear set. The sound.... WOW ... it will make you wet your pants...

I gotta a cbr f4i and I want my bike to have that same loud ( illegal ) sound cuz its sounds so dam good, MOTO GP like for those who have never herd........ But with my luck they dont make it for my bike, go figure! ... I was wondering if anyone has ever tried to make their own pipes to get a sound like that.

I know some guys will just take their muffler and run mid pip and header... but from what i have been told its all bad for the motor because of lack of back pressure...

so wtf is up!
