Will the Long Tube Competition Race Header System fit my 991.2 GT3 or GT3 RS?

Yes. The Long Tube Competition Race Header System fits the 2017-2019 991.2 Porsche 911 GT3 and the 2018-2019 991.2 GT3 RS with the 4.0L flat-six. It installs as a bolt-on and is designed to be removable, so it can come off for emissions testing and go back on afterward.

How does this differ from Fabspeed's other two header options?

This one is a system rather than a header set: it includes the side muffler bypass pipes built in. The Sport Headers with HJS Cats are headers with catalysts, for cars keeping emissions equipment. The Long Tube Race Headers are headers alone, no catalysts. This is the most complete of the three and priced accordingly.

Do I still need the separate side muffler bypass pipes?

No. The side muffler bypass function is integral to this system, which is the main reason it costs more than buying headers on their own. Ordering both would duplicate the same part of the exhaust.

Will it set a check engine light?

It may. Fabspeed states that installing competition headers can set one. That is expected on a system built for racing and track use rather than road compliance, and it is part of why Fabspeed designed the system to be removable for emissions testing.

What do the Burns Stainless collectors and Helical valves actually do?

The collectors are engineered so exhaust flow and gas velocity work together rather than trading off, which broadens the torque curve instead of just raising the peak. The Helical valves are built to an OEM standard used by Porsche, McLaren, Ferrari and Lamborghini, with Inconel T625 spindles on high-temperature bearings at both ends.

Why do I need to retorque the bolts?

Headers move as they come up to operating temperature the first time, and a seal that was perfect cold will not stay that way through the first heat cycle. Torque every exhaust bolt to the OEM specification once the car has been to full temperature and cooled. Skipping it is the most common cause of a leak on a new header system.

Description

Fabspeed Long Tube Competition Race Header System for 991.2 Porsche 911 GT3 & GT3 RS

The Long Tube Competition Race Header System is not a set of headers. It is a set of headers with the side muffler bypass pipes built into them, which is both why it costs more than Fabspeed’s other header options and why it does more. Everything from the cylinder heads to where the side mufflers used to be comes out as one engineered assembly, developed with Burns Stainless in California and refined on a DynoJet one change at a time. The collectors are Burns units designed around the synergy of high flow and high velocity. The valves are Helical, the supplier Porsche, McLaren, Ferrari and Lamborghini all use, with Inconel T625 spindles running on high-temperature bearings at both ends. It is built for racing, track and off-road use, and Fabspeed designed it to come off and go back on again for emissions testing.

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.
