Removed from a 2003 BMW 540i M sport that was recreationally road raced. The secondary cats were removed on this car and replaced with custom-bent 2.25\" stainless steel tube. In phenonomenal condition and can add a ton of growl or \"throatiness\" to your E39\'s grunt. O2 sensors can be tricked with two (2) spark plug unfoulers PER SIDE. I was able to successfully do so.
