Remember that ".045 aluminized steel tubing" is the same stuff that all those exhaust shops that stare with an "M" and have yellow logos use. I would not expect it to last any longer then any of their exhaust systems do. I still would like to see some numbers based in science and not theory, like dyno numbers where the ONLY change is the exhaust "manifold".

I still have never seen the price of one of these yet. By the looks of it, and the materials stated by the "manufacturer" I don't see more then about $30 to $50 worth of materials in the piece. With basic exhaust fabrication and welding skills I can't see more then an hour to fabricate one of these.

My opinions are based on my over 12 years of exhaust experience, mostly at those "M" yellow logo shops.
