Product Description

Our Porsche 958.2 Cayenne Turbo / Turbo S Valvetronic Exhaust System provides the best of both worlds, making it the perfect system for those who want to enjoy their vehicle both in the streets AND on the track. Two unique exhaust tones; one exhaust!

Valves Closed: When the valves are closed, the exhaust is routed through a perforated resonator pipe, allowing to air to escape and bounce around the muffler. This maintains a volume level similar to stock while increasing overall exhaust tone and reducing weight in the rear of the vehicle. 

Valves Open: When the valves are opened, the exhaust takes the path of least resistance, shooting down a stainless steel straight pipe, right through the muffler, and out of the vehicle. This shortcut that the valves open up is not perforated, so the air has only one place to go; right out of your vehicle. 

Unhappy with the dull exhaust note of his stock Cayenne, a good customer of ours requested that we unlock something special from the Twin Turbo platform. We were more than happy to do so, and crafted a rear exhaust section fitting of a Porsche. Our Valvetronic exhaust offers two unique exhaust tones; perfect for a vehicle that has multiple uses. With the valves open, our exhaust provides an exhilarating tone with a pleasing level of volume increase in the cabin without being overpowering. Close the valves, and you can enjoy a improvement in exhaust tone and quality without the significant increase in overall volume. 

We utilize the best valves in the business: Helical’s extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs and high-temperature bearings at both ends of the butterfly spindle.

Optional deluxe Quad Style Tips in your choice of finish to compliment the Cayenne's rear aesthetics and the enhanced exhaust note. Give your Cayenne Turbo the look and sound it deserves!

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.
