SOUL Performance X-Pipe with Slash Signature Satin Tips for 987.2 / 981 Porsche Boxster & Cayman / GT4

The SOUL Performance Bolt-On X-Pipe with Tips for the 987.2 / 981 Boxster and Cayman is a direct replacement for the factory “T” tip section, sharpening both sound and appearance without requiring a full rear exhaust swap. This assembly replaces the restrictive, crash-prone factory merge with a smooth cast T304L stainless X-pipe that allows exhaust pulses to cross over cleanly, reducing turbulence, improving flow, and yielding a crisper, more refined exhaust note with a sportier character in both normal driving and PSE sport modes, along with a subtle improvement in responsiveness and efficiency during spirited and highway driving. Paired here with SOUL’s Slash Cut Single Wall tips in Signature Satin, it delivers a purposeful, motorsport-inspired rear aesthetic with OEM-plus quality. The cast X-section features a smooth interior free of weld intrusion for durability and reliability, leveraging the same X design proven on SOUL’s full Boxster / Cayman systems, including record-setting track cars. Each unit is fixture-checked for precise fitment, thoroughly inspected, foam packed for safe delivery, and backed by SOUL’s renowned lifetime warranty for both street and track use.

Development

• In the factory “T” tip section of the Boxster / Cayman, exhaust gases collide with each other upon exiting the muffler, leading to turbulence and a negative impact on performance. This cost-cutting approach hampers efficiency. However, integrating a smooth, cast X-pipe into the rear section creates a more efficient flow path for the exhaust gases. As a result, a slight increase in gas mileage during cruising and improved power during aggressive acceleration can be expected.
• The casting of the interior is meticulously designed to be smooth, without any protrusions from welds. In non-cast designs, stress and potential lack of proper welding techniques may cause failure at this juncture. SOUL Performance Products has chosen to offer the most durable X-pipe solution. These X-sections have been extensively utilized in their comprehensive range of Boxster / Cayman exhaust systems, demonstrating exceptional performance, including being used on the fastest Boxster ever recorded at Watkins Glen. Furthermore, these X-pipes are backed by a lifetime track-use warranty, underlining their reliability. Cast components, like the one in question, have a proven track record in OEM applications and are widely regarded in the aftermarket performance industry, particularly for intake plenums and throttle bodies, as exemplified by IPD Plenums.

Construction

• SOUL Performance Products utilizes a cast T304L stainless steel X-pipe, which guarantees a smooth inner wall and a clean “X” section for maximum flow efficiency. Customers can personalize their exhaust system to match their preferences by choosing from a diverse range of options. These include single-wall 321 stainless tips, available in both slash-cut and straight-cut designs, as well as chrome double-wall tips with various finishes. Additionally, there are titanium single-wall tips offered that provide a significant weight reduction of nearly a pound compared to stainless steel tips. To ensure exceptional quality, each component undergoes meticulous quality checks and is thoroughly tested in a fixture to guarantee precise fitment. Before shipping, all items are thoughtfully foam packed, ensuring their safe and flawless arrival to customers.
