BBi Autosport Porsche 991 GT3 StreetCup Exhaust Bypass
BBi Autosport Porsche 991 GT3 StreetCup Exhaust Bypass
Now Available Through Pelican Parts!!!  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. We addressed those flaws when we designed our exhaust system for the 997 GT3. Most other aftermarket exhaust systems on the market replaces the secondary center 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. We took a more unorthodox approach and bypassed the much heavier primary side mufflers. The primary mufflers are weigh approximately 44 pounds total while our 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. Key Features
