Designed for racing, track events and off-road use, Fabspeed's Long Tube Competition Race Headers with integral Side Muffler Bypass Pipes are designed to maximize the horsepower and torque bolt-on potential of the Porsche 997 GT3/GT3RS engine by increasing exhaust flow from the engine cylinders straight into the exhaust system. This system was designed, incrementally dyno developed and maximizes engine power all throughout the powerband.
When the first 997 GT3 landed on North American soil, our engineering team immediately got to work and developed a Race Header to maximize the performance of the track weapon. Our original medium tube modular header design was very successful, but we were looking for more power. Consequently, we were approached to enhance a GT3 RS and welcomed the opportunity to refine our long tube header design further. After extensive development, including dyno and track testing of various designs, we've uncovered the correct formula to unlock the maximum performance and exhaust flow from the Porsche 997 GT3/GT3RS. There is no better designed and engineered race header system for the Porsche 997 GT3/GT3RS available worldwide. The Fabspeed Motorsport GT3 header was developed in conjunction with the racing engineers at Burns Stainless LLC Costa Mesa California. Burns Stainless is a World leader and innovator in stainless steel header design, testing and building high velocity merge collectors.
FEATURES:
BURNS STAINLESS COLLECTORS:
Bringing our headers to an end are Burns Stainless Collectors which combine high flow and high velocity to increase and broaden an engine's torque curve. Our decision to utilize Burns Stainless slip on collectors was easy, their superior design and Burns stainless unparalleled 30 years of proven performance in Worldwide motorsport competition.
OPTIMIZED SIDE MUFFLER BYPASS PIPES W/ HELICAL VALVES:
To provide the ultimate track solution for the 997 GT3/GT3RS, we are now utilizing premium Helical valves. We chose to use Helical Valves for their unprecedented quality - which have been proven by many OEM manufacturers such as Porsche themselves, McLaren, Ferrari, Lamborghini, and many more.
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.

Was there for Porsche club event. Staff was incredibly knowledgeable and helpful with my questions about track upgrades for my car. The place was as clean as an operating room. Attention to detail in their engineering and fabrication were impressive. Looking forward to having them do some work for me.
I reached out to Fabspeed via their chat feature on their website and made a deal with their representative on the spot. They called me within a matter of minutes to get my information and a few days later I had my exhaust for my 1988 Carrera. Perfect fit and finish! And did I mention it sounds great!

I had heard great things about Fabspeed from others in the industry but my expectations were definitely exceeded with this project. The team at Fabspeed went above and beyond when developing and building the exhaust system for our NSX. With the pictures and video commentary, they made us feel like we were a part of the action and that isn’t an easy to do when you are 800kms away and in another country. I know that there were many skilled hands that were involved with making this project come to life and I would like to extend our thanks to the entire team. Moreover, I’d like to take a minute to emphasize how much I appreciated having Alec quarterback this engagement. He was a key part in making this happen and was patient, professional, and extremely responsive at all hours of the day/night. The NSX was greatly missed while it was gone but it came back with a new set of lungs and the sound is much more fitting of a car in its class. We are already considering working with them on another project and I would highly recommend them.
Very special thank you to DJ at Fabspeed. DJ answered my call late in the business day. We chatted about exhaust options available for my air cooled Porsche. He was very patient and knowledgeable. I told him I'd call the next day to follow up as I wanted to do more research on their products. I call the next day, speak to DJ, and settle on several performance parts for my Porsche. Best part, all items were in stock and able to be picked up since I'm local to their shop. I arrive at the shop at the agreed upon time. Items were already packaged and ready for pick up. The cherry on top was an offer from DJ to tour the shop and see "where the magic happens." I really appreciated this and enjoyed hearing about how Fabspeed started and where it's headed. Now that I'm part of their community, I'm looking forward to attending their open houses. I will be back in the future. Fabspeed is more than a "shop." They want to build lasting relationships with their clients while remaining on the cutting edge of product development. Kudos to the entire team.
Just ordered some parts from Scott at Fabspeed and let me tell you--EXCELLENT customer service! I'm super excited to get my bypass pipes! After talking with Scott I definitely felt more comfortable with my decision to buy these pipes from this company!
