Review on BBK 1663 Performance Catalytic Converters by Marcus Price

This is a great product and the BBK fitted perfectly the first time. But it doesn't have the deep muscle car sound you'd expect from an off-road pipe. My last Mustang had an off-road pipe and it sounded very different than this one. But it allows my daily driver to be legal and allows me to pass government inspection with no problems. The sound is more reminiscent of a racing car.
