Hate to contradict someone on my side of the argument, but those aren't aftermarket pipes. When you have an 18-wheeler decelerating with that loud noise that's called a "Jake Brake". It uses energy from the compression of a diesel engine in sort of a reverse way. Not sure how it works exactly, but it has something to do with changing how the exhaust valves work in order to release some of the cylinder pressure from the piston chamber instead of using that pressure to push the piston back down in the cycle, so that additional pressure coming out of the cylinders is what's making that sound.

Ah, I knew I had heard of that but forgot what it was specifically. Thanks!
