SOUL Performance Sport X-Pipe Exhaust System w/ GT2 Signature Satin Tips for 991 Porsche 911 Turbo & S

SOUL Performance Products’ Sport X-Pipe Exhaust System for the Porsche 991 Turbo replaces the factory rear exhaust with a full catted, free-flowing T304L stainless assembly designed to support serious power and elevate the 3.8L twin-turbo flat-six with a sharper, more sophisticated soundtrack. A proprietary X-pipe with integrated mixing chamber, 3″ mandrel-bent tubing, and quad straight-through race resonators work together to reduce back pressure, improve velocity, and unleash an exhilarating blend of turbo wail, flat-six bark, and tasteful pops and burbles on overrun, all without triggering a check engine light when used as intended. Weighing about 14.4lb less than the factory rear section (30.6lb vs 45lb), the system not only improves sound and flow but also trims mass from the rear to enhance responsiveness. Finished here with SOUL’s Signature Satin GT2 Style Single Wall tips, it gives any 991.1 or 991.2 Turbo a more aggressive, motorsport-inspired rear profile that recalls Porsche’s GT cars while framing the diffuser and showcasing the upgraded hardware. Each Sport X-Pipe is hand-built from thick-wall .065″ T304L stainless, TIG welded, and fixture-checked for precise, direct bolt-on fitment with the factory catalyst sections and mounting points. Backed by SOUL Performance Products’ renowned Lifetime Warranty for both street and track use, this system is an ideal solution for 991 Turbo owners seeking a refined but unmistakably more intense exhaust note, reduced weight, and ample headroom for future power upgrades.

Development & Testing

• Soul Performance Products aimed to create an assertive catted system that offers a moderate increase in tone, accompanied by captivating pops and burbles upon deceleration, all without triggering a check engine light. Another key consideration was ensuring support for high power, which necessitated the use of 3″ tubing. Through experimentation, they introduced a mixing chamber into their X-pipe design. Thorough analysis in 3D CAD software revealed an overall velocity increase downstream of the mixing chamber, spanning various pressure and temperature levels. This results in optimal flow characteristics, reduced backpressure for higher horsepower output, and an enhanced sound quality for the system. The inclusion of quad race resonators significantly reduces drone while encouraging a more refined exhaust note. Additionally, the system was designed with modularity in mind, allowing for easy tip replacement, conversion back to factory catalytic converters, or the option to incorporate their pipes at any time.

Construction

• Crafted from mandrel bent T304L stainless steel tubing with a diameter of 3″ and a wall thickness of .065″, every Sport X-Pipe Exhaust System ensures exceptional durability. The system features straight-through race resonators designed with a full metal packing for maximum longevity. Laser-cut brackets are employed to ensure impeccable fitment. You have the flexibility to choose from a variety of hand-finished tip options, allowing you to achieve the desired aesthetic that best complements your 991. Alternatively, you can opt to reuse your factory tips.

HJS Catalysts

• Soul Performance Products utilizes the most exceptional catalytic converters renowned for their industry-leading flow and remarkable durability. These converters exhibit outstanding efficiency, meeting the stringent EURO 4 emission standards while facilitating increased flow, all without triggering a check engine light. The HD design incorporates premium triple foil winding, ensuring maximum strength. Additionally, the inclusion of a brazing stripe serves as an additional feature to enhance durability, preventing core movement or damage during sustained high horsepower abuse. Soul Performance Products deliberately employs a large and appropriately sized catalyst to enable maximum gains, leaving no room for compromises.

Sound

• The HJS catalytic converters excel in their exceptional flow, allowing for the passage of more turbo and flat-six sound. The incorporation of quad resonators adds a refined tone to the exhaust note while effectively reducing droning in the cabin. The overall volume level is perfectly suited for owners seeking a sophisticated increase in sound, offering a notably aggressive tone during heavy throttle inputs, while maintaining a mild and sporty presence during cruising.

Bolt On & Go

• Every exhaust undergoes rigorous testing in a dedicated fixture to ensure impeccable fitment. Following this, each exhaust is meticulously foam packed to guarantee its pristine condition upon arrival. Thorough installation instructions are included in the package, providing step-by-step guidance for a straightforward installation process suitable for most do-it-yourself enthusiasts.
