DEVELOPMENT AND TESTING: Need to leave the factory catalytic converters in place – or just want to get greater volume with a greater amount of pops and burbles on deceleration from your 991 Turbo? The SOUL X-Pipe Exhaust is the answer. We had modularity in mind – you can switch tips out or add our catted or catless pipes at any time. Support for high power was another consideration – necessitating 3″ tubing. We experimented with adding a mixing chamber into our X-pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system. Quad race resonators make a discernible difference in reducing drone while encouraging a more refined exhaust note.

SOUND: Enjoy an increase in sound from both the engine and turbos without any drone – experience an OEM+ tone that the Turbo should have sounded like leaving the factory.
CONSTRUCTION: Each system made from mandrel bent T304L 3″ .065″ wall stainless steel tubing, straight through race resonators with a full metal packing design for maximum durability, and laser cut brackets for perfect fitment. Choose from several hand finished tip options to get the look that suits your 991 the best – or reuse your factory tips. Mikalor Supra Heavy-Duty Clamps are included to securely hold our tips onto the system.
BOLT ON AND GO: Each exhaust is tested in a fixture to guarantee fitment and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
