has any one heard of this exhaust Pro 1, I bought it at a junk yard for cheap, i looked at it and it has a metal patch that says Pro 1 performance. its defenatly a good exhaust, sounds good, its made out of some kind of stainless steel it has a bronze look to the metal.

 

A lot of ebay and off-brand exhuasts have good welds and pretty good fitment. Put it on and see how it sounds/ performs.
