Fabspeed's Valvetronic Exhaust System is the ultimate catback setup for the ultimate streetable GT4 dual use street/track car. New anti-resonance technology makes for an even more enjoyable experience. This is the Finest system that money can buy. Seriously>
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 exaggerating. 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.
NOTE: For vehicles not equipped with a Porsche Sport Exhaust (PSE) / valves from the factory, a Fabspeed Valve Controller Kit is necessary to control the operation of the valves. Please choose the appropriate kit before ordering.
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, the your vehicle does not have PSE and you should select the standard exhaust option when checking out.

The GT4 sound is nice and aggressive with this exhaust. This makes the car sound like it actually feels beneath your seat. You'll get some exhaust drone at lower rpm and cracking the windows open a bit will help to make this tolerable at cruising speed so you don't end up with ringing ears. Overall I love the sound of this exhaust. The construction and carbon fiber tips are really nicely done too.
I could never let go of my 993 Carrera because I love the air cooled sound, very unique. I have to say the GT4 has it's own distinct tone that has my heart. The valvetronic exhaust amplified everything I love about the engine note and has turned it up to 11. This is paired with my Fabspeed Sport Headers and the volume is now on the high side which may not be for everyone, but where my 993 is the right level of rumble for leisurely driving the GT4 is a vivid reminder of Porsches racing history every time I give it gas now. Bravo!
I recently installed the Fabspeed Race Headers and Valvetronic Exhaust System on my Porsche GT4...or should I say, I recently came face to face with The God of Thunder. For me, the sound of a car is nearly paramount in the car experience. The GT4 with this Fabspeed setup is better than anything I have ever heard. Even beats my favorites of a screaming Ferrari V12, the Lexus LFA, the Porsche Carrera GT, and the
C7 LeMans Corvette. I would take this over any of those...and I don't say that lightly.
The setup I chose is not for the faint of heart. 7500 rpms with open windows in a tunnel would make Zeus himself cower. Kudos to Fabspeed and Porsche for attaining automotive perfection.
