The BBi Autosport 997 GT3 / RS Exhaust Side Bypass is a direct replacement for the factory primary side mufflers. The primary mufflers are weigh approximately 44 pounds total while the BBi pipes are 4 pounds in comparison. For durability and protection against corrosion, each system is meticulously TIG welded using 304 aerospace grade stainless tubing with lower carbon content. The result is a substantial reduction in weight behind the rear axle which significantly improves handling and less restriction to produce a much more aggressive exhaust note.
The BBi Autosport Porsche 997 GT3/GT3 RS Exhaust Side Bypass shaves over 40lbs of weight, improves airflow, and provides a much more aggressive exhaust note.
