Fabspeed Valvetronic Nordschleife Cat-Back Exhaust System for 992 Porsche 911 GT3 & GT3 RS

The Fabspeed Motorsport Valvetronic Nordschleife Cat-Back Exhaust System introduces the 992 GT3 to an authentic and exotic sports car sound, all while preserving the functionality of Porsche’s Sport Exhaust valvetronic push-button system (PSE). Their meticulous design process commenced with the comprehensive 3D laser scanning of the entire OEM exhaust system and the underside of the GT3’s flat 6 engine, utilizing the Creaform 700 Handscan. This allowed for the creation of a precise Solidworks 3D model of the exhaust. The subsequent CAD design phase, built upon this model, ensuring a seamless fit in line with Porsche Motorsport’s exacting standards. After numerous iterations, focusing on sound optimization and incremental dyno testing, they arrived at the decision to incorporate their signature cast 70mm 2.75″ x-pipe. This choice facilitated the synchronization of the two cylinder banks, aiding in exhaust scavenging and mitigating resonance. The exhaust valves employed are sourced from Helical Limited, a reputable manufacturer in the United Kingdom known for producing aerospace-quality exhaust valves. These valves, certified under ISO 9001, are the same trusted by renowned brands like Ferrari, McLaren, Pagani, Koeniggseeg, and Porsche for their GT cars. Fabspeed’s exhaust systems are crafted in-house, utilizing mandrel-bent T304 stainless steel, and they offer a selection of five different tip options to cater to individual preferences.

Sound

  • When PSE (Porsche sport exhaust) is deactivated, the valvetronic exhaust system offers a subtle increase in volume. However, when PSE is activated, it transforms the exhaust note of the 4.0L engine into a truly exotic sound, marked by a significant volume boost. The exhaust note evolves from the smooth purr of the OEM exhaust to the aggressive and race-bred snarl reminiscent of a 911 CUP car. The investment cast x-pipe, meticulously designed through CAD, plays a pivotal role in delivering the high-pitched and sporty sound characteristic of the GT3 sports car. Fabspeed’s commitment to excellence is underscored by their approach, involving the design and construction of four different exhaust systems to ensure they deliver only the very best in terms of both sports car sound and maximum power.

Power

  • This exhaust system enhances Porsche’s original design by increasing the pipe diameter from 2.5 inches to 2.75 inches (70mm) and replacing the factory h-pipe with our signature cast x-pipe. Through DynoJet testing, it revealed substantial benefits, yielding a remarkable +17.5 crank hp or +14whp (representing horsepower at the wheels) at 4200rpm. Additionally, there was a notable increase in torque at the lower end, with a gain of 17 ft/lbs at 4200rpm. These performance enhancements deliver a tangible improvement in driving experience, accompanied by significant rear weight reduction. It’s important to note that a 3″ x-pipe resulted in a loss of 15 ft/lbs of torque and a decrease of -10 HP compared to the 70mm option, highlighting the superiority of the latter choice. It’s a clear case of “buyer beware,” as larger is unequivocally not the right direction to take.

Features

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.
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.
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.
