We’re proud to announce availability of our 991 Turbo exhaust suite – from full system with bespoke tuning to bolt on tips.
EXHAUST 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. An 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 back pressure for higher HP, and enhances the sound quality of the Porsche exhaust system. Our custom Porsche 991 exhaust system includes quad race resonators which make a discernible difference in reducing drone while encouraging a more refined exhaust note.
EXHAUST 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.
EXHAUST 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! A custom Accessport map is available to pair with our system.
EXHAUST CONSTRUCTION: Each custom exhaust system is 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 custom exhaust tips onto the exhaust system.
WEIGHTS: Competition: approximately 19 lbs / 8.6 kg less than factory exhaust systems (26 lbs vs 45 lbs). Sport (catted): approximately 14.4 lbs / 6.5 kg less than factory exhaust components (30.6 lbs vs 45 lbs)
HJS CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – preventing the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!
CHECK ENGINE LIGHT?: Expect no CEL with our catted Sport X-Pipe Exhaust System. Catless, most likely, but chances can be reduced with O2 spacers.
LIFETIME WARRANTY: Enjoy your Soul custom exhaust systems with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
