SOUL Performance Sport Catalysts for 997.1 Porsche 911 Carrera (non PSE)

SOUL Performance Sport Catalytic Converter Downpipes for the Lamborghini Urus transform the 4.0L twin-turbo V8 from quick to truly ferocious, uncorking a harder-hitting sound and sharper response while keeping high-flow cats in place. Large 3-inch mandrel-bent T304L stainless tubing is paired with premium HJS HD 200-cell catalytic converters to dramatically cut backpressure, improve turbo response, and unleash a deep, throaty exhaust note with aggressive crackles that suit a super-SUV. Co-developed with Gintani to comfortably support big-power builds, these downpipes flow far better than stock yet are engineered to minimize the chance of check engine lights, making them an ideal match for tuning and additional bolt-ons. Each set fits all 2018+ Urus models, sheds about 5.7lbs compared to the factory sections, and is hand-built with CNC-cut flanges, back-purged TIG welds, and fixture-tested geometry for precise fitment. Rigorously quality-checked, foam packed for safe delivery, and backed by SOUL Performance’s renowned Lifetime Warranty, they deliver a no-compromise upgrade in sound, character, and performance.

Development

• The factory catalytic converters found in the 997.1 Carrera tend to be restrictive, making their upgrade a popular modification. SOUL undertook a fresh examination of the exhaust design, striving to develop the optimal solution. By conducting side-by-side sound comparisons between their split bank design and an X-pipe design, it was observed that an X-pipe configuration resulted in a hollower exhaust tone, eliminating desirable deeper frequencies unique to the 997.1 model, creating a noticeable difference. On the other hand, separating the banks enhanced volume and character, resulting in a deeper and fuller flat six sound with a touch of rasp, evoking an exhaust note reminiscent of air-cooled engines. Independent dyno testing conducted at Growler Motor Labs verified real and repeatable peak gains of 10whp and 14ft-lbs of torque, accompanied by a noticeable improvement in the mid RPM range. This upgrade enhances throttle response and overall drivability, rekindling the love for your Carrera with remarkable gains in both sound and power.
