On my '08 Nytro MTX there is 7" of space from the top of the Camo xtreme paddles to the bottom of the tunnel. I have a bike pipe I want to put on but it is 4" in diameter. Do you guys think that 3" of space between muffler and track is enough or is the track going to balloon at speed and hit the muffler? In other words how much space is needed between track and muffler? Any real world experience in this potential problem or is it safe to do without tearing up track or muffler? Thanks
