I bought a coffman sizzler exhaust system from him. He packaged it well, sent it on time but... When he removed the exhaust he must have broken the bolt that holds the pipe to the exhaust manifold. I have about 4 hours in trying to remove it, now I have to buy a helicoil kit and put a new thread in there. He knew about it when he sent it obviously, didnt say a thing. PMed him to say that was really uncool and havent heard anything back. I would say this counts as a negative experience. I am out the 30 bucks to buy a helicoil kit and out 4 hours of my life. Super uncool thing to do, passing your problem onto someone else.
