I sent an email question to FMF about a week ago, and still have not received an answer to the following questions. Can anyone here help me out? - Differences between the moto and S/X powerbomb headers. - Weight savings of the ti vs. stainless pb header. - Differences between the std. and euro Q mufflers. P.S. Anyone running a powerbomb with the stock muffler and a WB insert? I just bought a 02 WR426 and the header is bent. thanks.
