Our in-frame pipe is HUGE! It is the best all around pipe on the market. Using our snowmobile FAT pipe technology, we built this pipe to have a big midrange hit and pull, with incredible top end! These pipes work extremely well with ported motors. The mufflers are custom built with a CNC Billet aluminum end cap so that it won't blow out or fall apart!
NOTE: The 350 pipes will work on motors from 350's up to about a 430cc. For 440cc motors and above we do offer a big bore version of the inframe pipe.
