I think my entire gibson system was about $400 and came with the type of bends that many prefer for a free flow system. The hardest part was the turbo connection as you need to be on top to get it set up so I was abler to get a lift at the local mil car shop and put it up and down easily. As to straight pipes and quiet I cant tell ya, but I know if yo have a dodge (not in this case) it will drive ya nutsw in no time. So if going to replace get a good aluminized system unless you live in high salt area then consider the pricer stainless, but even then an aluminized will last a long time.
