Description

SOUL Performance Competition Headers for 987.2 Porsche Boxster / Cayman

SOUL Performance’s Competition Headers for 987.2 Porsche Boxster and Cayman replace the heavy, restrictive factory manifolds with a free-flowing, track-focused header solution that delivers stronger response, reduced operating temperatures, and a more aggressive flat-six tone. Developed specifically for the 987.2 platform, the design features properly sized 2in runners and optimized collectors to extract maximum performance from the 3.4L engine while still producing strong gains on the 2.9L. Constructed from T304L stainless steel with port-matched flanges and smooth-radius primary tubing, each set is rigorously quality-checked, fixture-tested for precise fitment, and foam packed for safe delivery, with new high-grade hardware included for the header-to-exhaust flanges and detailed installation instructions in the box.

Development and Testing

SOUL Performance developed a dedicated application for the 987.2 platform, carefully sizing the 2in runners and collectors to extract maximum power from the 3.4L engine while still delivering strong gains on the 2.9L. Dynojet testing on SOUL’s project Cayman S (PDK), when paired with the SOUL Valved Exhaust System, showed peak gains of 9whp and 10ft-lbs of torque at 4,100rpm.

Construction

SOUL Performance’s precision-engineered headers are meticulously fabricated from T304L stainless steel and designed to maximize power gains through proven flow-focused details. Port-matched flanges, smooth-radius primary tubing, and flow-optimized collectors work together to improve exhaust efficiency. Every set is rigorously quality-checked prior to shipping.

Bolt-On and Go

Each SOUL Performance product is test-fit in a dedicated fixture to verify precise fitment, then foam packed to help ensure it arrives in perfect condition. Detailed installation instructions are included for a straightforward install that most DIY enthusiasts can complete. New high-grade hardware is provided for the header-to-exhaust flanges.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
