Porsche 991 Turbo SOUL 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. Quad race resonators make a discernible difference in reducing drone while encouraging a more refined exhaust note.

DYNO-PROVEN POWER

Third party testing was performed on a Mustang Dyno at R/T Tuning. Baseline power with SOUL Competition X-Pipe Exhaust System was 542 whp and 629 ft-lbs of torque. A COBB Accessport base map pushed power to 581 whp and 733 ft-lbs of torque. A custom Protune pushed peak power to 606 whp and 749 ft-lbs of torque!

SATISFYING OUND

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.

HAND-CRAFTED 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 ensure perfect fitment and then foamed 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.
