YFZ 450 Top End

I just bought a 2005 YFZ 450, and I raced my brother's stock Raptor. On top side he might have 2 mph on me, so I was wondering if I add a pipe, filter, and rejet, would I gain any top end to hang with the Rappy?

it costs like 125 per shaft and it spins around and hits the rocker arms pushing the valvles down and letting the gas/air mixtures into your cyclinder
