I was up at my dealer the other day and saw a laser with the engine wrapped up with a plastic bag. I asked what happened to that, because I'm nosey. He said that the guy called and asked how much a new muffler was for it. My dealer replied with a price of like $120 or something. So this guy decides to take to his buddy so he can weld the muffler. Well he fixed the pipe, later that day a piece of this guys weld got sucked back inot the engine and blew the engine!!! Ended up costing him $1700. OUCH!!
