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

SOUL Performance Bolt-On X-Pipe with Straight Cut Single Wall Signature Satin Tips for the 987.2 / 981 Boxster and Cayman is a simple, bolt-on way to wake up both the look and sound of the car while keeping the stock rear mufflers in place. The restrictive factory “T” tip section is replaced with a smooth cast T304L stainless X-pipe, allowing exhaust pulses to cross over cleanly, reducing turbulence for better flow, a crisper, more refined exhaust note, and a subtle improvement in response when you get on the throttle. Straight cut single wall tips, formed from 321 stainless and finished in SOUL’s Signature Satin, fill out the rear valance with a clean, motorsport-inspired aesthetic that reads OEM-plus rather than flashy. Engineered as a true direct bolt-on for all 2009–2016 987.2 / 981 Boxster and Cayman models with factory exhaust or Porsche Sport Exhaust (PSE), each assembly is fixture-checked for precise fitment, thoroughly quality-inspected, carefully foam packed for shipment, and backed by SOUL Performance’s renowned Lifetime Warranty for confident use on both street and track.

Development

• The factory “T” tip section in the Boxster / Cayman models allows exhaust gases to collide within the muffler before exiting the tips, as a cost-cutting measure. However, this approach creates turbulence and negatively impacts performance. To overcome this limitation, SOUL Performance Products incorporates a smooth and cast X-pipe into the rear section, enabling a more efficient flow path for the exhaust gases. This enhancement results in a small increase in gas mileage during cruising and delivers more power when accelerating aggressively.
• The interior casting of the X-pipe is designed to be smooth, without any protrusions from welds. This is in contrast to non-cast designs that may fail at this junction due to stress and potential welding issues. SOUL Performance Products has made a deliberate and conscientious decision to provide the most durable X-pipe solution possible. Moreover, these X-sections have been successfully implemented across their entire line of Boxster / Cayman exhaust systems, which have a proven track record of performance, including being utilized on the fastest Boxster ever recorded at Watkins Glen. These exhaust systems are warrantied for track use throughout their lifespan. Cast components, such as the X-pipe, have been proven effective in OEM applications for years and are endorsed by IPD Plenums, a renowned aftermarket performance leader known for their intake plenums and throttle bodies.

Construction

• To achieve optimal flow, a cast T304L stainless steel X-pipe is utilized, boasting a smooth inner wall and clean “X” section. This design ensures maximum flow efficiency. Personalize your exhaust system according to your preferences by selecting from a range of options. Choose from single-wall 321 stainless tips available in slash cut or straight cut styles, or opt for chrome double-wall tips in various finishes, all allowing you to customize your exhaust to suit your taste. For those seeking lightweight options, titanium single wall tips are also available, providing a weight reduction of nearly one pound compared to stainless steel tips.
• To guarantee impeccable quality, each component undergoes rigorous quality checks, is tested in a fixture to ensure precise fitment, and is then carefully foam packed to ensure it arrives in perfect condition.
