The JBA system is really stainless. Different grades of stainless steel have different magnetic properties based on the content. Just google "stainless steel magnetic" and you'll get the explanation.
I looked at all of the systems out before choosing to go with the JBA. In the end, it was the best sound and power gains. It sounds like a muscle car without being annoying and it look hot on the car.
