I want to put a jury rigged muffler on the existing exhaust of the above quadrunner or use a plain jc whitney small car muffler....anything but the $ 169 dollar replacement that they want to sell me. The muffler it has on it is too loud and I'll be using it in a quiet farm area...don't want to bother the neighbors. Have any of you rigged a second muffler sort of like the universal stealth systems. I aint worried about it being pretty and awsum'. How about taking it to a muffler shop and letting them weld one on?...
