SOUL Performance Street Exhaust Package with Slash Cut Tips for 982 Porsche 718 GT4 RS / Spyder RS

Development and Testing

• SOUL Performance developed its Valved Exhaust System to maximize sound and performance while still offering true cruising civility. A full 3-inch X-pipe design delivers a high-pitched motorsport flat-six tone with the valves open and a more subdued character with the valves closed, and pairing it with Competition or Resonated Over Axle Pipes further uncorks factory restrictions for added response, power, and volume. To eliminate the drone that can come with increased output, SOUL Performance engineered and tested dedicated “drone canisters” tuned to target the low-to-mid 2,000 RPM range, shifting the drone zone down the rev range and significantly reducing peak frequencies. Because this architecture is designed around aftermarket OAPs, SOUL Performance’s Street Package pairs the Valved Exhaust with optional Competition OAPs for maximum volume or Resonated OAPs for a smoother, more restrained tone and even lower drone, with track-friendly canister access and optional block-off kits planned to drop 8.5lb.

Construction

• Each system is assembled in-house in the USA using mandrel-bent, thick-wall 0.065″ T304L stainless steel. SOUL Performance employs back-purged TIG welding with ARCAL™ Prime argon gas to ensure proper weld penetration and long-term durability. Precision water-jet-cut flanges are manufactured to ISO 9001:2015 standards with tight tolerances of +/- 0.003 inches for exceptional accuracy. Over Axle Pipes are fabricated on thick-gauge aluminum fixtures that act as effective heat sinks during welding, helping prevent warping of both the components and the fixtures to maintain consistent, OEM-quality fitment.

Exhaust Tip Selection

• For drivers who want to retain the factory appearance, SOUL Performance notes that the system can be run with OEM exhaust tips. However, the OEM tips use a much smaller inlet diameter, which forces a neck-down in the exhaust path that introduces a restriction and reduces overall performance. To maximize results on the GT4 RS, SOUL Performance strongly recommends their high-performance exhaust tips, engineered to match the full 3-inch system with no compromises.

Features

• Slash cut tips in a Signature Satin or Matte Black finish
• Over Axle Pipes + Valved Exhaust remove primary GT4 RS restrictions
• True 3-inch flow path throughout via oval OAP tubing and X-pipe design
• Dual-mode valves, aggressive open tone, refined closed cruising
• Drone canisters tuned for low-to-mid 2,000 RPM resonance reduction
• Choice of Competition or Resonated OAPs for volume vs smoothness
• USA-built 0.065″ T304L stainless with back-purged TIG welds
• ISO 9001:2015 water-jet flanges (+/- 0.003″) for precision fitment
• OEM tips compatible, but 3-inch SOUL tips recommended to avoid neck-down restriction

Applications

• Porsche 718 Cayman GT4 RS: 982C | 2022-2025 | MA2.75 – 4.0L F6
• Porsche 718 Spyder RS: 982 | 2024-2025 | MA2.75 – 4.0L F6

Notes

• Due to the GT3-derived engine’s higher output in 718 RS models and the additional heat it produces, SOUL Performance strongly recommends adding a thermal management solution to Over Axle Pipe products to protect surrounding components and bodywork.
