FMF Powerbomb Header??

[nofear911]

Does anyone have a PowerBomb header? Do you like it? Where do you notice improvements? Do you notice weaker points in powerband anywhere after it was installed? Did you have to rejet after installation?
I have a 425 with stock carb, stock headpipe, and stock valvetrain except for lowend Hot Cam, with a K&N, procircuit T-4 Slipon, and higher compression piston. Would the PowerBomb help torque in bottomend and hp in top end?

YOu'll need a larger pilot jet. I run a 42 with mine. I don't believe i changed the main jet at all. You'll notice more power from top to bottom, no loss anywere..:cool:

After I had my 416, cam, and porting done, I was running a full Big Gun system that (I thought) was putting out good power. Then I put on the FMF sytem. All I can say is WOW! Big gains everywhere!!!! I love it, and will put the same exhaust on my YFZ.
