Most of the shops use Aluimized pipe now days and the pipes last a heck of alot longer. If you buy Stainless pipe I believe you would get a full pipe bend turns vs mandrel bend which caves in or flatens the inside of the pipe. Most muffler shops have the mandrel style machine to make their bends.
Looking at there picture they are using a standrad manderl bender.
The price sounds a little high to me for Aluminized pipe. I just priced out a 350cu chevy with Magna Flows for $375.00. You use Glass Packs they should be cheaper.
