Fabspeed Porsche 991 Twin Turbo maximum performance
 

Fabspeed offers an exhaust suite that is sure to give you exactly what you are looking for, whether you want to concentrate on maximum track-competition performance, street use, or a blend of both.

No matter what system you go with, the performance optimization starts with the headers. Our Porsche 991/ 991.2 Twin Turbo Sport Headers improve exhaust flow for a power increase and significant increase in sports car sound, all while saving 6 lbs. from the rear of the vehicle. Our Sport Headers feature a 3-into-1 high velocity investment cast merge collectors for improved exhaust scavenging and a much faster turbo boost. Fabspeed headers are Dyno tested to verify maximum power and are a direct bolt-on replacement for factory OEM headers with no cutting or welding required.

Unleash the full song from your 991/ 991.2 Twin Turbo's flat-6 engine by replacing the heavy and restrictive OEM factory mufflers and multiple 700-cell catalytic converters. From the factory, Porsche equipped the 991/ 991.2 Twin Turbo models with an extremely powerful 3.8 L flat-6 engine setting a performance benchmark yet again for sports-cars and super-cars around the world. Despite the impressive performance, the soundtrack is decidedly lackluster, more like a high-powered vacuum than a sports car, without any indication as to the sheer power of the engine that fuels the fire. The exhaust note is far too sedated to be representative of a proper sports car. It has been Fabspeed Motorsport’s primary mission for over 20 years to design systems that bring out the true potential of Porsches flat-6 engine, the 3.8L flat-6, and our Supersport X-Pipe Exhaust System excels in all aspects.

Our Porsche 991/ 991.2 Twin Turbo Supersport X-Pipe Exhaust System is a high performance free flowing 70mm X-Pipe design that can be ordered for two different applications; STREET or RACE.

The 991/ 991.2 TT STREET application features our HJS German imported 200 CPSI Catalytic Converters, high-flow sport race cats designed for maximum flow and power that flow 93-95% of a straight pipe. Fabspeed's Supersport Exhaust System significantly decreases turbo spool time and back pressure, providing for quicker acceleration and increasing power over the factory system by 25 WHP and 31 ft/lbs of TQ at 4250 RPM – all without triggering a CEL. These are built utilizing the world’s best catalytic converters made by HJS Emissions Technologies in Germany. Fabspeed is the sole distributor of HJS Cats in North and South America. If your HJS German imported Catalytic Convertors are not imported form Fabspeed, caveat emptor; buyer beware of bootleg or counterfeit catalytic convertors!

The 991/ 991.2 TT RACE application uses our Cat Bypass Pipes, straight pipes that increase exhaust flow from the competition headers to the mufflers, slightly improving top end power and sound throughout the RPM range. The exhaust flowing from the straight pipes into the X-Pipe is an intoxicating combo, adding an aggressive exhaust, a noticeable improvement in throttle response, and savings 5 lbs. compared to our STREET application. This system is for those who want to most competition performance out of their vehicle, and when paired with an ECU tune, can significantly increase power and torque of the factory system.

We also offer our Porsche 991/ 991.2 Twin Turbo Supersport X-Pipe in a Valvetronic dual sound/dual tone variant. Our engineers have spent countless hours of hands on development with the Fabspeed Valvetronic Supersport X-Pipe Exhaust System with investment cast X-Pipe to extract the absolute best of both mild and wild exhaust notes from the 991/ 991.2Twin Turbo. The results speak for themselves.

With the valves closed, enjoy our refined Supersport 70mm X-Pipe exhaust tone. Exhaust flow is channeled through Fabspeed's signature 70mm Quad-Resonated investment cast X-pipe. We engineered it specifically to smooth out exhaust pulses for a sophisticated and exotic exhaust note while being as free flowing as possible. The tone is perfect for cruising around town or long highway drives.

At the push of a button, the valves open, and the exhaust is free to rocket straight out from the Sport Cats or Cat Bypass Pipes with an aggressive roar. The full story of Porsche's turbocharged 3.8 L flat-6 is unleashed, along with an intoxicating barrage of crackles and pops upon deceleration and downshifting. This system truly needs to be heard and felt in person to be appreciated. Now any 991/ 991.2 Twin Turbo owner can have sports car sound virtually identical to the GT2 RS. In fact, the Cats we use are even a higher-flow version of the Cats used in the factory Porsche GT2 RS System. You can only get these engineering marvels through Fabspeed Motorsport!

We mentioned we use the world’s best cats, but we also use the world’s highest quality valves in our products. What makes our Valvetronic Supersport X-Pipe Exhaust Systems unique, are the Helical Valves by Helical UK, known for their high-temperature bearings at both ends of the butterfly spindle, cast stainless steel valve body with stiffening ribs for ultimate durability, and increased reliability - proven in racing and high volume OEM use have been proven by many of the top manufacturers. When you order a Fabspeed system you’re getting the same valves that Porsche installs in each and every 991/ 991.2 GT3/GT3 RS as well as the new GT2 RS

We just finished up a complete performance transformation of this 2015 991 Turbo. They started off with our Street Performance Package but after a taste of the 991 Turbo's true potential, they wanted more. We transformed it into our Race Performance Package by swapping out the Sport Cats for a Catbypass but didn't stop there. We added @bydesign_motorsportTurbo and Intercooler, @ipdplenums Intake Plenum and Y Pipe, @cobbtuning PDK Flash and a retune to bring it all together. When it was all said and done we were all blown away by this build, especially the customer! What do you guys think?

Nice marketing thread, "maximum performance" look forward to seeing some real numbers, specific config (parts list, cooling, fuel, trans upgrade?) and final dyno sheet. More power, love it ! Sharp looking products.

what kind of dyno numbers did you end up with?

Tuned for 93.

You guys were featured in a Car Fix episode where the guys were upgrading a 991 Turbo S to run a 1/4 mile in 9 sec range. They didn't get there in the episode I watched. Was the client ever able to get there?

We are waiting on the 1/4 mile time.
