They're not the best thing out there, but they are inexpensive...which is good, because you will have to replace them quite often, due to the fiberglass packing blowing out. I've got some on my exhaust and am about to get them cut out and replaced by straight pipes.
The exhaust was quiet when I first installed it, but now the glasspacks have blown out and it is getting louder and louder. If my exhaust is going to be loud, I would rather it be free-flowing as well :rolleyes:
I would get a quality one, but don't feel like paying the price. Like everything else in this world...you get what you pay for.
