Do the Boost Logic Race Headers for 991 GT3 need a tune?

Plan on one. Boost Logic does not state a tune requirement or publish power figures for the Race Headers for 991 GT3 cars, but long tube headers change how the engine breathes, and most owners pair them with a calibration from their tuner. Agree the tune with your tuner before the headers go on rather than after.

Which finish should I choose?

Boost Logic lists the headers in coated or polished finishes and does not show a price difference between them. The photos show the headers in bare metal. Coating changes the look under the car and is often chosen for heat management, so tell Bulletproof Automotive which finish you want when you order.

Are the headers sold as a pair?

Yes, as photographed. Boost Logic sells them under one listing and the photos show a left and a right header, one for each bank of the flat-six. Boost Logic does not list gaskets or mounting hardware as included, so plan to source new header gaskets and hardware for the install or ask Bulletproof Automotive to confirm.

Do they fit the 991.2 GT3 with the 4.0 liter engine?

Not confirmed. Boost Logic lists the headers for the 991 GT3 without separating the 991.1, with its 3.8 liter engine, from the 991.2, with its 4.0 liter engine. Because the two engines differ, confirm your model year with Bulletproof Automotive before ordering, and we will check fitment with Boost Logic.

Can the headers be used on the street?

They are sold as race headers for closed-course and competition use. Emissions and noise rules differ by state, so check the regulations where the car is registered and driven before fitting them to a road car. Bulletproof Automotive can talk through the other Boost Logic exhaust parts for the 991 GT3 if road use matters.

Description

Boost Logic Long Tube Race Headers for 991 Porsche 911 GT3

Boost Logic’s Long Tube Race Headers for 991 Porsche 911 GT3 are a left and right pair of long tube headers for the naturally aspirated GT3 flat-six, one for each cylinder bank. The photos show each header running three primaries into a collector, with welded tube sections and flanges at the cylinder head. Boost Logic lists coated and polished finishes and publishes no other specification, so the case for this part rests on the long tube layout itself; it belongs on a track-focused GT3 rather than a car that has to stay stock.

Long tube header design for each cylinder bank
Three primaries per side merging into a collector, as shown in the Boost Logic photos
Left and right headers photographed as a pair

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.

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.
