FMF power bomb

How much would this help my WR 400 1998. I have an FMF mega max pipe on it right now with the proper jetting. Would i have to change the jetting also with the change in the header. thanks in advance for the info.

The Power Bomb was Recommended AND TESTED by Dirt Rider aways back, no matter what silencer was on the bike.

I am no jetting guy, but I think you'd be all set up with your jetting as long as you keep your silencer on there.

WZ/YR (you choose!) with ALL YZ mods, de-octopused, DSP Doug Henry airbox w/ velocity stack, FMF PowerBomb header, Stroker SX-1 silencer, SS front brake line, OEM YZ tank, IMS YZ seat.
