SOUL Performance Competition Muffler Bypass Exhaust for 993 Porsche 911 Carrera

SOUL Performance Products delivers a complete high-flow exhaust solution for the 993 that brings out an unmistakable air-cooled chorus while improving power and response. The system features a premium X-pipe section that feeds into a large-diameter, non-restrictive muffler-bypass rear exhaust, maintaining a true 2.5-inch flow path throughout. Dedicated configurations are available for the various factory flange combinations (Bischoff and Gillet) and for both OBD1 and OBD2 vehicles, ensuring 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 set out to create a system suited to both street enthusiasts and RWB builders. By re-evaluating the 993 Carrera from the ground up, SOUL Performance engineered 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 is engineered to bring out everything enthusiasts love about air-cooled sound without turning the car into something unpleasant to drive. The tone delivers a strong roar and burble that is undeniably loud, yet controlled enough for real street use without punishing the ears. Downshifts produce crisp crackles and pops, while idle settles into a rich burble that makes it clear the car is something special. Suited for weekend cruising and show-car duty alike, the system draws positive attention wherever it goes, and optional resonators are available for drivers who want a more civilized experience on a street-driven car.

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, while every component is fixture test-fit to confirm proper fitment before being foam packed to help ensure it arrives in perfect condition.
