SOUL Performance Exhaust System for 991.2 Porsche 911 Carrera (non PSE)

SOUL Performance Products’ Performance Exhaust System with Anti-Drone Tubes for the Porsche 991.2 Carrera Base (without PSE) wakes up the muted 3.0L twin-turbo flat-six by replacing the rear muffler section with a free-flowing T304L stainless assembly engineered specifically to add tone while keeping highway manners in check. Designed around the known 1,800-2,200rpm drone zone of non-PSE cars, SOUL’s tuned Helmholtz anti-drone tubes target and cancel unwanted frequencies so you get a deeper, more classic 911 sound under light throttle and a far more aggressive bark when you lean into it, without the headache on long drives. Hand-built from thick-wall .065″ mandrel-bent T304L stainless and back-purged TIG welded in SOUL’s Willow Grove, PA facility, the system offers a straight, efficient flow path yet only adds .65lb over the factory components. This configuration is tailored for base 991.2 Carrera models running factory catalytic converters and reuses the OEM exhaust tips, preserving a clean, factory appearance with a dramatically more engaging soundtrack. Each system is fixture-checked for precise, bolt-on fitment, foam packed for safe delivery, and backed by SOUL’s renowned Lifetime Warranty for both street and track use, making it a compelling solution for owners who want real sound and refinement without compromising everyday usability.

Development & Testing

• SOUL Performance Products embarked on developing a rear exhaust system that embodies simplicity, lightweight construction, and aggressive characteristics while still ensuring optimal drivability. With a focus on addressing the droning issues typically encountered in the 1800-2200rpm range with aftermarket exhausts on 991.2 non-PSE equipped cars, they based their entire system around resolving this primary concern. Extensive testing was conducted, exploring various configurations that incorporated resonators, Helmholtz resonators (also known as anti-drone tubes), straight pipes, and a basic x-pipe to identify the most effective solution. The evaluation included tests performed with and without their Sport Catalytic Converters, considering their popularity as a common modification. Ultimately, resonators were found to diminish the overall engine tone and volume without adequately addressing the drone. However, helmholtz resonators, when engineered and implemented correctly, proved to be an efficient means of reducing undesirable frequencies. SOUL Performance Products’ final design, born from this rigorous testing, has proven to deliver the optimal results for this specific application, meeting their stringent standards for sound quality and drivability.
• In search of the most aggressive sound and lightweight option? SOUL Performance Products also provides the exhaust system without anti-drone tubes, offering a lighter and more cost-effective alternative. While maintaining the same exterior volume and tone, this variation reduces drone without compromising on the desired auditory experience.

Construction

• Every exhaust is meticulously handcrafted using mandrel-bent T304L stainless steel with a thick wall measuring 0.065 inches. These exhausts undergo rigorous in-house quality checks to ensure impeccable craftsmanship. To guarantee proper weld penetration and long-lasting performance, the welding process employs back purging techniques with TIG welding.

Bolt On & Go

• Every product undergoes meticulous testing in a dedicated fixture to guarantee an impeccable fitment. Following this, it is carefully foam packed to ensure safe and flawless arrival. The package includes comprehensive installation instructions, enabling a straightforward installation process that can be easily carried out by most do-it-yourself enthusiasts.
