Fabspeed’s Valvetronic Exhaust System is the ultimate cat-back performance exhaust for the ultimate street-drivable GT4 dual-use street/track car. With new anti-resonance technology, it offers the world’s best enjoyable driving experience.
Sound
We’re delighted to offer a premium exhaust solution for the Porsche Cayman/Spyder GT4. The Valvetronic Exhaust provides two distinct tones depending on the valve position: mild and aggressive wild. We made it a priority to maintain civility around town with the valves closed, and we’ve succeeded. You’ll be able to cruise into 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 focus on you. We’re not exaggerating. This system will put an ear-to-ear smile on even the most miserly of faces.
Power
When combined with Fabspeed’s Race Headers, our Valvetronic Exhaust System allows you to push 420HP out of your GT4! Even with Sport Headers, which come in at 408 Horsepower, the power gains are impressive. 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 significant difference in street drivability with the long gearing of the GT4. Fabspeed systems undergo 3D laser light scanning, CAD designing, and dyno testing, as well as street, racetrack, and Autobahn validation.

DOES MY CAR HAVE “PSE”?
The Porsche Sport Exhaust – better known as PSE – was a factory option available on many late-model Porsches. You can quickly and easily determine if your vehicle is equipped with PSE by taking a look at your center console. If your console has a button on it with an “exhaust tip” icon (see photo), then your vehicle is equipped with PSE, and you should select the PSE option when adding this product to your cart. If you do not see this button, then your vehicle does not have PSE, and you should select the standard exhaust option when checking out.
