SOUL Performance Sport Muffler Bypass Exhaust for 993 Porsche 911 Carrera

SOUL Performance Products offers a complete high-flow exhaust solution for the 993 that delivers an unmistakable air-cooled chorus while improving power and response. High-flow catalytic converters are integrated into a premium X-pipe section, which feeds into a large-diameter, non-restrictive muffler-bypass rear exhaust. Dedicated configurations for Bischoff and Gillet flange combinations, along with OBD1 and OBD2-specific designs, ensure the ECU receives proper, balanced O2 sensor readings from all cylinders.

Development

• SOUL Performance recognized that the 993’s air-cooled engine deserves an exhaust that lets it truly sing, and developed a system suited for both street enthusiasts and RWB builds. By taking a fresh look at the 993 Carrera, SOUL Performance engineered exhaust components around large-diameter 2.5-inch piping to deliver maximum power gains over the factory system. For OBD1 applications, SOUL Performance uses a centrally located single O2 sensor bung to provide the most accurate, balanced readings from all cylinders, avoiding the compromises of shared OBD1 / OBD2 designs where one bung is plugged and an offset sensor primarily monitors a single bank.

Sound

• SOUL Performance Products engineered this system to deliver the best of air-cooled character, a strong roar and rich burble without an overbearing cabin experience. Downshifts produce crisp crackles and pops, and idle settles into a deep burble that makes it clear the car is something special. At low throttle and low RPM, the exhaust remains composed for casual cruising and longer drives. High-flow catalytic converters paired with the X-pipe help keep the engine note smooth and prevent rasp while maintaining strong flow. The result is an ideal setup for weekend cruising and show-car duty, drawing the right kind of attention wherever it goes.

Construction

• Each exhaust is assembled by SOUL Performance from thick-wall 2.5-inch diameter, 0.065-inch T304L stainless steel and is rigorously quality-checked in-house. Smooth mandrel bends and thick flanges support long-term durability, and every component is fixture test-fit to confirm proper fitment before being foam packed to help ensure it arrives in perfect condition.
