Shedding weight is one of simplest ways to add performance to your Porsche. Unfortunately, reducing weight on the already slim GT3 is rarely an inexpensive task and the factory exhaust system is already very well designed for optimum power delivery. The only drawbacks to the factory system is a muted exhaust note that was designed to comply with the local laws and appeal to a wide customer base, and the excess weight.
BBi addressed those flaws when designing their exhaust system for the 991 GT3/RS. Most other aftermarket exhaust systems on the market replaces the secondary centre muffler and the performance gains and weight savings are minimal. The factory secondary exhaust weights approximately 20 pounds and the average secondary muffler bypass weighs approximately 7 pounds, which equates to only 13 pounds of weight savings.
BBi took a more unorthodox approach and bypassed the much heavier primary side mufflers. The primary mufflers weigh approximately 44 pounds in total while bypass 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.
