Racefit exhaust

[Destin07]

Please tell me somebody knows where to find a sound clip of a RACEFIT GROWLER exhaust on a hayabusa. Does anybody have this exhaust, know anything about performance gain?? I've got a buddy that has a 07 GSXR 1000 and saw a 10HP increase within 1 hour and on the same dyno after putting a Growler exhaust, air filter, and programmer on his bike!

This is just sad

The only thing I can offer up is this:
Sport Rider-motorcycle sport bike exhaust pipe sound clips

Perhaps with a little more patience someone else can help.

!0 HP can probably be achieved with just about any pipe, air filter and PC don,t you think?
