Any MX system will give you an earth moving power gain.
Do the exhaust system first, as it is the only thing holding the bike back.

i think you'll find that the free mods with a jd jetting kit or GYTR jetting kit will squeeze a lot of performance out of the WR.

the aftermarket exhaust will be like icing on the cake. my buddies have had good success with the white bros E2 and pro circuit Ti-4. i've got the FMF powercore 4 with a quiet insert that i like.
