SOUL Performance Sport X-Pipe Exhaust System w/ Straight 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 engineered to support serious power while adding a sophisticated edge to the 3.8L twin-turbo flat-six. A proprietary X-pipe with integrated mixing chamber, 3″ mandrel-bent tubing, and quad straight-through race resonators work together to reduce backpressure, sharpen response, and unleash a harder-hitting turbo wail and flat-six bark, complete with pops and burbles on overrun, without triggering check engine lights when used as intended. Weighing roughly 14.4 lb less than the factory components (30.6 lb vs 45 lb), the system not only improves sound and flow but also trims mass from the rear of the car for a more responsive feel. Finished here with SOUL’s Signature Satin Straight Cut Single Wall tips, it gives the rear of any 991.1 or 991.2 Turbo a purposeful, motorsport-inspired look that frames the diffuser while allowing owners to showcase 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 factory catalyst sections and mounting points, and every system is backed by SOUL Performance Products’ renowned Lifetime Warranty for both street and track use – making it an ideal one-and-done solution for 991 Turbo owners seeking more sound, more character, and more 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 catless pipes at any time.

Construction

• Crafted from mandrel bent T304L stainless steel tubing with a diameter of 3″ and a wall thickness of .065″, each Sport X-Pipe Exhaust System exhibits exceptional durability. The system incorporates straight-through race resonators featuring a full metal packing design. Laser-cut brackets are meticulously employed to ensure precise fitment. You have the freedom to select from a range of meticulously hand-finished tip options that best complement your 991, or alternatively, you can opt to reuse your factory tips.

Sound

• The HJS catalytic converters excel in their flow capabilities, allowing an amplified presence of turbo and flat-six sounds. Quad resonators are integrated to further refine the tone and minimize cabin droning. The resulting volume strikes a perfect balance, providing owners seeking a sophisticated sound enhancement with an aggressive note during intense throttle inputs, while maintaining a mild and sporty presence during cruising.

HJS Catalysts

• SOUL Performance Products incorporates the most exceptional catalytic converters available, renowned for their unparalleled flow and durability in the industry. These converters exhibit exceptional efficiency, meeting rigorous EURO 4 emission standards while permitting increased flow, all without triggering a check engine light. The HD design employs premium triple foil winding, ensuring utmost strength. An additional feature, the brazing stripe, enhances durability by preventing core movement or damage under sustained high horsepower abuse. SOUL Performance Products deliberately selects a large and appropriately sized catalyst to enable maximum gains, leaving no room for compromises in performance.

Bolt On & Go

• Every exhaust system undergoes meticulous testing in a dedicated fixture to guarantee flawless fitment. Subsequently, each exhaust is carefully foam packed to ensure it arrives in pristine condition. Furthermore, the package includes comprehensive installation instructions, facilitating a straightforward installation process suitable for most do-it-yourself enthusiasts.
