the header pipe on the WR is good standard, it's unlikely you can gain much here. i fitted the FMF powerbomb header recently & i think it's a little stronger in the midrange. it takes about 1 bhp to feel the difference, so that would be about right.

the "silencer" is worth at most 2/3 bhp across the board which you can really feel. the higher figures-like 7bhp- come from the fact that an open pipe hangs on longer & therefore at say, 11,000-11,500rpm, there's a big gap.

i ride my at 15,000 rpm so this is right in the meaty part of the powerband! not.
