Does anyone know the best full exhaust system for the kfx 450? thanks!

 

Many say DASA... that's about all I know.

Myself, I think piping a 4 stroke is a bit over rated. But they say with this KFX, if you do an aftermarket intake, exhaust, and fuel controller it really makes a remarkable difference.

Myself, I'm wondering if the intake and fuel controller is not most of the gain...

But I do have to admit these things don't sound very racey with the stock silencer and arrestor installed. But they sound NUTS with it removed and the end cap re-installed. But I think you need a fuel controller to run that way.

 

ive heard that hmf gives you huge power gains. also yoshi's. but duster you are right i think dasa is the best on the market

 

I did a Yoshi full RS-3 comp system on my KFX 400 with a jet kit and a K&N filter with no box lid and it made a HUGE difference in power judging by the seat of my pants!! I was not impressed when I first got the quad but after doing that, it made me change my mind.....
