SOUL Porsche 997.1 Turbo Competition X-Pipe Exhaust System

DEVELOPMENT AND TESTING: We wanted to get as aggressive as possible while minimizing drone – greater volume with a greater amount of pops and burbles on deceleration. 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. Helmholtz resonators were engineered to target and reduce droning in the 2000-3000 RPM range. Quad race resonators make a discernible difference in reducing drone while encouraging a more refined exhaust note.

SOUND: You’ll be treated to a chorus of crackles upon letting off of the throttle. Comfort mode calms down the burbling for civil cruising. The exhaust makes itself known in the cabin without being overly aggressive.

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 997 the best – or reuse your factory tips.

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.
