SOUL Performance X-Pipe Exhaust System for 991 Porsche 911 Turbo

SOUL Performance X-Pipe Exhaust for the Porsche 991 Turbo is built for owners who want a louder, more characterful car while keeping their factory catalytic converters and OEM tips. Designed for all 991.1 and 991.2 Turbo models (except the Turbo S Exclusive Series), this system replaces the rear exhaust sections with a proprietary X-pipe layout using full 3-inch T304L stainless tubing and quad race resonators. The result is freer flow, meaningful weight savings over the stock components, and a vivid increase in flat-six engine note and turbo wail, all tuned for an OEM+ sound with no drone on the highway. By reusing the factory tips, the car retains its understated stock appearance while hiding a far more engaging exhaust behind the bumper. Each system is a direct bolt-on with included hardware and instructions, hand-built with mandrel bends and laser-cut brackets for precise fitment, and backed by SOUL Performance’s renowned Lifetime Warranty for both street and track use.

Development & Testing

• Whether you need to retain the factory catalytic converters or simply desire a louder exhaust with pronounced pops and burbles during deceleration for your 991 Turbo, the ideal solution lies in the SOUL X-Pipe Exhaust. SOUL Performance developed this exhaust system with modularity in mind, allowing you to interchange tips or incorporate catted or free flow pipes as desired. Additionally, they opted for 3″ tubing to accommodate high-power applications to ensure ample support.
• In their quest for optimal performance, SOUL Performance conducted experiments involving the inclusion of a mixing chamber within their X-pipe design. Detailed analysis using 3D CAD software revealed a notable increase in downstream velocity across various measured pressure and temperature levels. This design optimization translates to improved flow characteristics, reduced backpressure for enhanced horsepower, and an overall improvement in sound quality.
• Furthermore, the inclusion of quad race resonators in the system proves instrumental in minimizing drone while simultaneously promoting a refined exhaust note. With these meticulously engineered features, SOUL Performance has created an exhaust system that strikes the perfect balance between performance, acoustics, and modularity, catering to the preferences and requirements of discerning enthusiasts.

Construction

• Each exhaust system is meticulously crafted from mandrel bent T304L stainless steel tubing, with a generous diameter of 3″ and a wall thickness of .065″ for optimal performance and durability. The inclusion of straight-through race resonators, featuring a full metal packing design, further enhances the system’s longevity and ensures maximum efficiency in sound attenuation. Additionally, laser-cut brackets are incorporated into the design to guarantee a precise and seamless fitment.
• To personalize the look of your 991, a variety of hand-finished tip options are available, allowing you to select the one that best complements your vehicle’s aesthetic. Alternatively, you also have the option to reuse your factory tips. As a testament to their commitment to quality, each system is equipped with Mikalor Supra Heavy-Duty Clamps. These clamps provide secure and reliable fastening, ensuring that the tips remain securely attached to the exhaust system throughout your driving experiences.

Sound

• Indulge in a heightened auditory experience with an amplified sound emanating from both the engine and turbos, all while enjoying a drone-free environment. The SOUL X-Pipe Exhaust delivers an OEM+ tone that impeccably captures the essence of how the Turbo should have sounded straight from the factory. This exhaust system brings forth an enhanced and captivating sound profile, enriching the overall driving experience and complementing the performance capabilities of the vehicle. With SOUL Performance’s meticulous attention to detail and engineering prowess, the result is an exhaust system that perfectly aligns with the Turbo’s inherent character, elevating it to new auditory heights.
