Get the absolute most power and sound from your 992 Twin Turbo without any check engine lights. This system exhaust mimics the valves open configuration of a 991 GT2 exhaust and because of the modular design if you find the setup too loud for everyday driving you can use the optional muffler adapter pipes so that you can reinstall the factory muffler or our Valvetronic Maxflo Exhaust.
SOUND:
This system provides an aggressive sound that matches the incredible power and speed of the 992 Turbo. Expect a significant increase in volume over stock more turbo spooling sounds, while burbles and pops on deceleration are much louder and sharper.
POWER:
This is the most free-flowing exhaust design possible while still maintaining catalytic converters. When testing on our AWD Dynojet power was up across the board. Down low, the Turbo spools faster and harder, netting 23.7 WHP and 41.5 ft/lbs of TQ at 3000 RPM. Max power gains are at 5300 RPM where it gained 47.7 WHP and 47.1 ft/lbs of TQ. That's a gain of 54 HP at the crank! See our dyno graph above for more details.
FEATURES:
• Fits all Porsche 992 Twin Turbo / Twin Turbo S vehicles, coupe and cabriolet worldwide (2021+)
• Massive power gains of 47.7 WHP and 47.1 ft/lbs of TQ
• Saves 25 lbs / 11.3 KGs compared to stock
• Modular design allows you to switch between the GT2RS Style Outlets and the stock muffler or Fabspeed Valvetronic Exhaust while retaining the sport cats
• Included valve bracket prevents any chance of the electronic valves triggering a CEL
• Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel
• Laser scanned and CAD designed for perfect OEM fitment using an Ametek Handyscan 700
• Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
• 200-cell HJS German imported catalytic converters will flow 92% of a straight pipe with no CEL (Check Engine Light)
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
Why we choose HJS catalytic converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Fabspeed's Valvetronic Exhaust System is the ultimate cat back setup for the ultimate street able track car.
SOUND: We're proud to offer a premium exhaust solution for the Porsche Cayman GT4. Our Valvetronic Exhaust offers two distinct tones depending on valve position: mild and wild. It was important to retain civility around town with valves closed, mission accomplished. You'll be able to enter your neighborhood after a midnight joyride without having to explain yourself at the next HOA meeting. Open the valves, and you'll be treated to a glorious roar befitting of the GT4. Burbles and backfires erupt in abundance, and downshifts summon a bark that will make all eyes and ears around focus on you. We're not exagerating. This system will put an ear-to-ear smile on the most miserly of faces.
POWER: When combined with Fabspeed's Race Headers, our Valvetronic Exhaust System allows you to push 375 whp out of your GT4! Even with Sport Headers coming in at 371 whp, the gains in power are as impressive as the sound. The Fabspeed exhaust suite completely eliminates the torque dip in the 3500 RPM range and offers power gains all the way through redline. The increase in low end power will make a great difference in street driveability with the long gearing of the GT4.
FINISH: Full polished T304L stainless steel, beautifully welded together and finished off with premium carbon fiber shrouded tips which fit the rear bumper of the GT4 like a finely tailored suit.
