In the end most systems are Stainless Steel and robot tig welded. A reputable name is what makes the price sky rocket. Don't get me wrong, you do get what you pay for, but for an exhaust.......
I can't say to much, I waited for well over 7 months to get a Berk exhaust. I just knew what I was looking for in a CBE system. But for those looking for a cheap alternative and don't have the extra $$ because of this crappy economy,
I say go for it!
