Does anyone know when the next issue (Oct. I think) of ATVSport mag. should be hitting the shelves? It's supposed to have an exhaust shootout on the 400EX, and I'm hoping they have the WB e-series and Supertrapp IDS2 in there, because I can't decide which to get. Do you guys have anything (good or bad) to say about these slip-on silencers?

 

White Brothers is AWESOME with the righ jetting but inporper jetting the pipe only souds good but LOSE power, also here that super trap is junk. The top[ 3 are WB, DMC dual, and Big Gunn
