Porsche 991 GT3 Street Cup Exhaust Bypass


Shedding weight is one of the 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 drawback 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 they designed the exhaust system for the 991 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 weighs about 20 lbs. and the average secondary muffle bypass weighs about 7 lbs., which equates to only 13 lbs. of weight savings.

BBi took a more unorthodox approach and bypassed the much heavier primary side mufflers. The primary mufflers weigh about 14 lbs. total while the bypass pipes are 4 lbs., 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 is less restricting, allowing a much more pronounced and aggressive exhaust note.

  • Produces deep aggressive exhaust notes
  • Significant weight reduction of 40 lbs.
