whenever i had my tractor muffler on my rubicon you could see the fire comming back through the pipe at dark, it wouldnt reach the end of the muffler but it still looked really cool. people would ride behind me with there lights off so they could see itwhat we need is a flame thrower kit to keep people off ours asses when riding, it would be pretty cool at night
