Description

SOUL Performance Street Long-Tube Headers for 987.1 Porsche Boxster / Cayman

SOUL Performance Products’ Long Tube Street Headers for the Porsche 987.1 Boxster and Cayman are built around large-diameter, free-flowing HJS 200-cell catalytic converters and true long-tube runners to unlock significant gains in power, throttle response, and classic flat-six character across both 2.7L and 3.4L applications.Optimized 1.75″ primary runners and collectors are specifically sized for the 987.1 platform, with merge spikes in each collector to smooth exhaust flow and help the engine pull harder through the rev range rather than relying on a generic, one-size-fits-all design. Each header set is hand-assembled from T304L stainless steel with thick, water jet cut flanges made to ISO 9001:2015 standards for long-term durability and precise sealing, then rigorously quality checked in-house at SOUL’s Willow Grove, PA facility. The premium HJS 200-cell catalysts offer industry-leading flow and durability while meeting strict EURO 3 efficiency targets, greatly reducing the likelihood of check engine lights compared to lesser cores. Designed as a direct bolt-on for all 2005-2008 987.1 Boxster and Cayman models, these headers integrate cleanly with the factory exhaust, include new hardware, and are backed by SOUL’s renowned Lifetime Warranty for street and track use making them a go-to solution for owners seeking real performance gains without sacrificing reliability.

Development & Sound

The stock header design is a basic, widely manufactured part that lacks performance capabilities. SOUL Performance Products, however, took a different approach, specifically for the 987.1 platform. They paid close attention to properly sizing the runners at 1.75″ and integrated top-notch spikes into the collectors. This innovative design allows for extracting optimal power from the 3.4L engine while also generating significant gains from the 2.7L variant.

Construction

Every set of 987.1 headers is meticulously constructed using T304L stainless steel and subjected to thorough in-house quality checks. These headers feature merge spikes that are skillfully integrated to enhance exhaust flow, resulting in heightened power output. Additionally, the headers are equipped with water jet cut flanges that are of substantial thickness and adhere to ISO 9001:2015 standards, ensuring the product’s precise fitment and long-lasting durability.

HJS Catalysts

SOUL Performance Products utilizes the finest catalytic converters renowned for their exceptional flow and longevity in the industry. These converters possess remarkable efficiency, enabling compliance with stringent EURO 3 emission standards while simultaneously facilitating improved flow. As a result, the likelihood of triggering a check engine light is significantly minimized. The HJS HF design incorporates premium double-foil winding, delivering unparalleled strength and durability.

Bolt On & Go

Every set of headers with catalytic converters is meticulously constructed and undergoes rigorous testing within a robust aluminum fixture of substantial thickness. This meticulous process prevents any warping issues and guarantees flawless fitment. Additionally, the headers are carefully foam packed to safeguard them during shipping, ensuring they arrive in impeccable condition. The package also includes new, top-grade hardware specifically designed for secure attachment between the header and exhaust flange.

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.
