We would like to take a quick moment to present Flying L Racing’s Ruby Star Porsche 991.1 GT3 RS that we recently swapped out the bulky OEM side mufflers and replaced it with our BBi StreetCup Exhaust Bypass to reduce weight and deliver an aggressive exhaust note that matches the car's race-bred DNA. The side bypass is an excellent alternative to our popular center section exhaust bypass for those prefer a more aggressive Cup Car like sound and maximum weight savings. The factory secondary center exhaust weighs approximately 13 & 19 pounds for the Titanium RS and Stainless non-RS versions and our center section bypass weighs 8 pounds. This equates to only 5 or 11 pounds of weight savings depending on the variant.
To save the maximum weight, we took the same approach as Porsche with their Cup Cars, and bypassed the much heavier primary side mufflers. As shown on the scale, the primary mufflers are weigh approximately 46 pounds total for both the RS and non RS while our BBi bypass pipes are 5 pounds in comparison. That equates to a substantial weight reduction of 89% compared to the original weight of the OEM muffler that we replaced. For durability and protection against corrosion, each set is meticulously TIG welded using 304 aerospace grade stainless tubing with lower carbon content.
