What are the SOUL Performance 997 GT3 headers?

The SOUL Performance 997 GT3 headers are street headers built in-house for the Porsche 997 and 997.2 GT3 and GT3 RS. They feature large-diameter, free-flowing 300-cell high-flow catalysts with optimized cast flanges, billet CNC head flanges, and back-purged TIG welding for maximum gains in power, throttle response, and exhaust tone with no check engine lights.

What makes the billet CNC head flanges significant on the 997 GT3 headers?

The billet CNC head flanges allow for a more efficient transition from the exhaust ports into the runners and add extra strength in a high-stress area, preventing cracking from repeated hard use during track days.

Will the SOUL Performance 997 GT3 headers trigger a check engine light?

No. The SOUL Performance 997 GT3 headers are designed to increase exhaust flow without triggering a check engine light.

Is an ECU tune required?

A tune is not required to fit the 997 GT3 headers. Many owners add a tune to maximize the performance gains.

Is professional installation recommended?

Yes. We recommend installing the Street Headers through a qualified technician to ensure correct fitment and a proper seal.

Description

SOUL Performance Street Headers for 997 Porsche 911 GT3 / GT3 RS

The SOUL Performance 997 GT3 headers are street headers built around large-diameter, free-flowing high-flow catalysts with optimized cast flanges and runners for maximum gains in power, throttle response, and tone from the GT3’s high-revving flat-six. Increased exhaust flow without a check engine light. Direct bolt-on installation. Backed by the SOUL Performance Lifetime Warranty for street and track use.

Development and Testing

Even with the 911 GT3’s elite motorsports pedigree, regulations and external pressures forced compromises to be made. Primary tubing length, runner diameter, and merge collection efficiency are limited even in the most purpose-built of applications, and these compromises come at the cost of sound and power. Addressing the restrictive factory headers is the place to start for immediate results. The SOUL Performance 997 GT3 headers are built around large-diameter, free-flowing high-flow catalysts with optimized cast flanges and runners for maximum gains in power, throttle response, and tone from the GT3’s high-revving flat-six. The result is an amplification of the exhaust system rearward, a proper emphasis on the flat-six’s sound, and construction built to withstand aggressive driving in the most demanding environments. Billet CNC head flanges allow for a more efficient transition from exhaust ports into the runners while adding extra strength in a high-stress area, preventing cracking from repeated hard use during track days.

Hand-Crafted Construction

Each header is built from mandrel-bent, durable 0.065-inch T304L stainless steel tubing. The premium SOUL-designed 300-cell high-flow catalyst features a custom-specced precious metal catalyst coating and triple metal matrix core. Back-purged TIG welding with ARCAL Prime argon gas ensures proper weld penetration for exceptional strength and longevity. Water-jet-cut brackets are manufactured to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. Thick-gauge aluminum fixtures act as heat sinks during welding to prevent warpage.

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.
