Our Porsche E3 Cayenne S 2.9L TT 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!

FEATURES:

  • Fits all Porsche E3 Cayenne S 2.9L Twin Turbo Models (2019+) (Does NOT Fit Hybird Models) WithPorsche Sport Exhaust (PSE) - Not Compatible with Standard Exhaust (Coming Soon)
  • Direct replacement slip-on maxflo muffler with electronic valves for the stock OEM system
  • Saves weight, 6 pounds 2.5KG versus stock Porsche muffler and adds another 8HP with much superlative sports car sound and growl. Front X pipe slip on replacement saves 4 pounds 2 KG and really wakes up and adds quality sound.
  • Electronically controlled exhaust valves like the factory Porsche design. Reuse factory Plug & Play electronic motors on the Fabspeed Maxflo exhaust.
  • Slip on system for rear section with front section X pipe that ties the exhaust together on both sides of the V6. The stock exhaust is 2 separate channels from from catalytic converters to tips. Fabspeed Motorsport USA included two ingenious Unique X pipes to harness the 6 cylinder engines exhaust pulse together to guarantee much better sound and power all in one!

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 exhilaratingtone 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 rearaesthetics and theenhanced exhaust note. Give your Cayenne S the look and sound it deserves!

(Direct replacement for your existing Porsche Sport Exhaust (PSE) Option)

NOTE:

  • For vehicles equipped with a Porsche Sport Exhaust (PSE) / valves from the factory. Not compatible with the standard exhaust at the moment - Coming Soon!
  • Bolt-On Installation - Minor cutting required at factory exhaust break point to install the Fabspeed product (Reference Dimple Locations on OEM)

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.

Great for a growing kid
Size: Large, Color: Sky Blue, Size: Large, Color: Sky Blue
Good quality for a good price. My teen is outgrowing his medium clothes and into larges so it fit slightly big which I expected but that just means he should be able to wear it to his fall dance as well. Nice material, not see through at all even after dancing all night and sweating. Exact color blue as pictured. Very happy over all.

Great shirt for the price.
Size: 4X-Large Big Tall, Color: Sky Blue
Shirt fit perfectly and was true to size. The material seems to be of a good quality for the price, and it is surprisingly light weight when worn. I use these as daily shirts, and have only used it once so far. Did well after washing and required little to no ironing out of the dryer. Very impressed with the item so far.

Perfect for my teenage son.
Size: Small, Color: Blue White Pinstripe
My son has worn this shirt many times to temple for bar mitzvah services. It’s soft doesn’t wrinkle easily and very comfortable for him to wear. He receives many compliments on it. This is a relatively thin shirt sizing was accurate. Fabric is what I would consider Nice quality. Color is spot on.

Surprising quality for such a cheap item
Size: 4X-Large Big Tall, Color: Navy White Diamond Geo
Surprisingly good fit. The material is a bit thin and if you're wearing it on a cold day, I would recommend an undershirt. The collars could use a good starching for a more modern look. As it stands with an open jacket, the large collar makes it look a little dated. If you have 20 dollars and need a shirt you could certainly do worse.
