What are the SOUL Performance 981 GT4 long tube headers?

The SOUL Performance 981 GT4 long tube headers are built around large-diameter, free-flowing sport cats with long tube runners for maximum power, throttle response, and flat-six engine tone from the 3.8L engine. They add performance without triggering a check engine light.

What power gains can I expect?

Third-party dyno testing on a Dyno Dynamics dynamometer showed gains of 30 whp when paired with a tune, with 12 whp unlocked by the headers alone after the tune had been applied.

Will these headers trigger a check engine light?

No. The SOUL Performance 981 GT4 long tube headers are designed to add performance without triggering a check engine light.

Which 981 models does this fit?

The SOUL Performance 981 GT4 long tube headers fit the Porsche Cayman GT4, Boxster Spyder, and Cayman Clubsport (2015-2016), as listed in the Applications section above.

SOUL Performance Long Tube Headers w/ Sport Cats for 981 Porsche Boxster Spyder & Cayman GT4

The SOUL Performance 981 GT4 long tube headers are built around large-diameter, free-flowing sport cats with long tube runners for maximum gains in power, throttle response, and flat-six engine tone from the 3.8L engine. Add performance without triggering a check engine light. Direct bolt-on installation with instructions included. Backed by the SOUL Performance Lifetime Warranty.

Development and Testing

Creating a unique application for the 981 platform, SOUL focused on sizing the runners (2 inches) and collectors correctly to extract maximum power from the 3.8L engine. Appropriately sized sport cats were chosen to flow enough power for sustained high RPM use, where the GT4 is at home. Third-party dyno testing on a Dyno Dynamics dynamometer revealed gains of 30 whp when paired with a tune, with 12 whp unlocked by the SOUL Performance 981 GT4 long tube headers alone after the tune had been applied.

Hand-Crafted Construction

Each header is assembled from T304L stainless steel and rigorously quality-checked in-house. Proven design elements, including port-matched flanges, smooth-radius primary tubing, and collectors that optimize exhaust flow, work together to maximize power gains.

Bolt-On and Go

Every SOUL Performance 981 GT4 long tube header is tested in a fixture to ensure perfect fitment. Thorough installation instructions are included for a straightforward install that most DIY enthusiasts can perform.

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.
