the system came and the box was all torn up but all the pieces seemed to be there except for two of the nuts for the muffler clamps. The pipe all went together well but the directions were lacking. with a little test fitting and measuring we were able to get the kit to fit nicely. The hardware is all very nice and the kit looks and sounds great. Very deep rumble on the LBZ. I would say that this is not a simply bolt on kit, but the parts are very good quality and with a little work it makes a great system.
