Man, i wish i had a camera this last week, cuz i just set up my exhaust for my MTD. i put about 15" of 1 1/4" of straightpipe, then after the 15'' i put an extra 12'' of some old 1 1/2" chrome vacum cleaner pipes making a nice lookin chrome sidepipe. then when i ran it the engine had much better low end power, but kinda lacked the high end power. but with that setup, it sounded NOICE!
