Why is the GM Performance Exhaust System better than the rest?
A. The GM Performance Exhaust System is designed, tested, and manufactured specifically for your GM vehicle. GM Performance Exhaust Systems are made entirely of the highest-quality 300-Series stainless steel; this includes the cat-back exhaust, the semi-polished mufflers, and polished tips and fasteners. With semi-polished muffler and adjustable and interchangeable exhaust tips, the GM Performance Exhaust System gives GM vehicles owners the opportunity to take vehicle personalization to the next level. The 300-Series stainless steel resists surface corrosion altogether, unlike 400-Series stainless steel used on non-GM exhaust systems. GM engineers complete numerous tests to ensure that the GM Performance Exhaust System performs as designed and meets or exceeds all federal decibel regulations without the need for additional modifications to the vehicle.
