anybody alittle disappointed in the small amount of flange area in the race pipe to header area compared to stock flanges.................i mean why pay two big bills for a tuned pipe 4 two stroke engines that depend completely on harmonics for tuning to produce increased performance to have a leak at the header pipe!!!!! i'm looking for a pipe and the pictures i'm seeing clearly show exhaust leakage+the old wear mark way over a quarter inch farther up the pipe where the old stock flange was!!!!!!!!
