slightly off course and ive asked this before, do any of think their is any performance to be gained by redesigning the muffler  portion and going to a center style mount? ive seen lots of trx guys run a center mount style rear muffler portion that slightly shortens the total length and has a straighter shoot out vs bending the pipe to go around the frame to clear the factory air box. most high hp builds do not run an air box so why design a pipe to clear a part that isnt used??? on the pic from the first posts, looks like their are unnecessary bends to clear an air box that isnt there.
