well i made the switch from the stock box with the k&n filter to the bhaf and i must say that it is only a verry small difference in sound between the two. the k& n had been good,so ill see what works out better. now i need to get hold of a heat shield for it. what to do ? i cant seem to figure out what im going to use. larry b shield looks good but what about the others? like the 8" stove pipe or the l shaped one i cant seem to get a dealer or the template. any sugestions??
