Instructions were on the back of an advertisement for Gibson. It did not explain where to mount the c clamps in relation to the joints. It described clamps by letters, but no letters were present, only numbers. I broke one c clamp over tightening because it wouldn't squeeze the pipe where I had the clamp. Really good fit and finish though. Great sound at start up and accelerating.
