I lost my left one going to Boston - don't know how but it was loose to start. Drove home and was pissed by the uneven exhaust note. Literaly beat the right one out with a wooden handle and the claw hammer. Much better - for performance type sound. But there is a drawback.... it drones bad now. Going up a hill anywhere from 2k-4krmp in 3rd or 4th and the resonance is unbelievable.
