SOUL Performance Exhaust System with Dual Wall Tips for 987.2 Porsche Boxster / Cayman

The SOUL Performance Products Valved Exhaust System for the Porsche 987.2 Cayman and Boxster is engineered to deliver a true night-and-day change in character at the press of a button. With the valves closed, exhaust flow is routed through SOUL’s mufflers for a refined, sporty tone with minimal drone at highway speeds (with stock headers) and the ability to cruise quietly when needed. Open the valves and the system shifts to a louder, more engaging flat-six sound built for spirited driving and track use.  Developed and tested on SOUL’s own Project 987.2 Cayman S, Dynojet testing recorded peak gains of 8 whp and 11 ft-lbs at 4,100rpm when paired with SOUL Long Tube Street Headers. Construction features mandrel-bent T304L stainless steel tubing with 2.5-inch OD over-axle pipes, fortified-case mufflers packed with durable sound-deadening material, and a flow path that changes between modes to keep the tone controlled in quiet mode and fuller and more robust with the valves open. The system installs as a direct bolt-on, weighs 5lbs less than factory components, and includes a valve controller kit (required for non-PSE cars and optional for PSE cars for manual valve override).

Development

• Porsche equips the 987.2 Cayman and Boxster with a restrictive, bulky exhaust system that holds back the platform’s natural power and flat-six sound. SOUL Performance developed its Valved Exhaust System on its own Project 987.2 Cayman S to ensure the difference between valve modes is both noticeable and refined, even when paired with aftermarket headers. During Dynojet testing, SOUL recorded peak gains of 8 whp and 11 ft-lbs of torque at 4,100 RPM when combined with SOUL Long Tube Street Headers on the project Cayman S. The system is currently used on SOUL’s daily-driven Cayman S and is consistently track tested on the Project Cayman R. Because aftermarket Boxster and Cayman exhaust hangers and supports are often prone to cracking or failure, SOUL’s fortified brackets are designed to help prevent damage during extended street driving and track days.

Construction

• Each SOUL Performance system is constructed from mandrel-bent T304L stainless steel tubing, including 2.5-inch OD over-axle pipes, and features mufflers with fortified casings for long-term durability. With the valves closed, exhaust gases are routed through the SOUL muffler, which is packed with high-quality sound-deadening material engineered to withstand abuse and resist blowout over time while effectively minimizing drone. In this mode, gases pass through the muffler and exit through perforations into the outer piping. With the valves open, exhaust gases flow through large 2.5-inch piping, while the perforations allow the flow to interact with the muffler to create a fuller, more robust tone. A variety of 321 stainless exhaust tips is available in multiple styles and finishes, with custom options offered upon request, and titanium single-wall tips are also available to save nearly a pound compared to stainless tips.

Bolt On & Go

• Every exhaust system undergoes rigorous quality checks to ensure the highest standards are met. Additionally, each exhaust is meticulously tested in a fixture to guarantee precise fitment, providing a seamless installation experience. To safeguard against any damage during transportation, each exhaust is carefully foam packed, ensuring it arrives in impeccable condition.
