Best valved exhaust for Porsche Cayenne 955 and 957

Your vehicle.

The first Cayenne came in two types, the 955 and then the 957, and with several engines, naturally aspirated or turbocharged. The Rog exhaust covers the 2002 to 2010 model years; your VIN tells us your engine before manufacturing.

What holds back the factory sound

The first Cayenne was tuned for versatility and comfort: its factory exhaust barely hints at the engine, even under load, whereas a Porsche carries a real sound heritage.

What the Rog exhaust changes

With the Rog exhaust, valves open, the Cayenne takes on a deep voice that thickens as you accelerate, with crackles on the overrun; valves closed, it becomes the calm SUV of family journeys again. The measurable gain, for its part, comes from the front section and a remap.

Cayenne S 955, 4.5 V8: 340 hp, 420 Nm.

With the sports front section and a remap by a tuner, the product page publishes 455 hp and 600 Nm at Stage 2.

Choosing your exhaust.

Five decisions, in this order: each one builds on the one before, and the last no longer affects the sound. Before you start, here is what you are buying.

Your exhaust, in two parts

1. 1

   Step 1 of 5: Sound: the voice of your car

   An exhaust's sound is shaped in three places: its character, which you choose here; its intensity, which depends on the front section (step 3); and the volume of the moment, which you set with the valves (step 4).

   The character

   On this exhaust, the character is not an option you choose: it has a single voice, designed for this engine. You can go straight to the material.

   Our advice. Here, the character is that of the exhaust itself: you choose your sound at step 3, with the front section, and day to day with the valves. Valved exhaust: how it works, price and vehicle inspection.

2. 2

   Step 2 of 5: Material: stainless steel or titanium

   The material changes three things: weight, sound and durability. It is a genuine technical choice, not just a matter of looks.

   304 stainless steel

   Base price

   Weight

   Baseline

   Sound

   Full and rounded

   Durability

   Withstands salt and winter

   Tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.

   Titanium

   Optional

   Weight

   Around 40% lighter

   Sound

   Metallic, crystal-clear

   Durability

   Does not rust

   Around 40% lighter than stainless steel for the same design, with a more metallic sound that turns crystal-clear at high revs. You then choose it in one of three colours, at the same price (step 5).

   Our advice. Stainless steel for a first purchase and everyday use; titanium if you are chasing every kilo and want a higher-pitched note at high revs. Over time, both last. Stainless steel or titanium: what really changes.

3. 3

   Step 3 of 5: Front section: sports catalytic converter or decat

   On your Cayenne, the front section depends on the engine: on the turbocharged versions, it is the downpipes, at the turbo outlets; on the naturally aspirated versions, it is the manifolds. This is where the catalytic converters sit, and after the exhaust itself, it is the part that matters most, for the sound as much as for the breathing. It is optional; on the product page, this choice is called “Manifold”, whatever the part, and your VIN tells us which one is right for you.

   Cat-back only

   Included

   7/10

   Factory catalytic converter retained

   You keep the factory front section. It already makes it a different car: most of our customers start here.

   200-cell sports catalytic converter

   Optional

   8/10

   Road use and inspection

   Emissions control stays in place, flow improves markedly and the sound gains presence. Our choice for the road.

   100-cell sports catalytic converter

   Optional

   9/10

   Inspection: depends on the vehicle

   Half as many cells: more breathing and more aggression at high revs.

   Decat

   Optional

   10/10

   Track use

   No emissions control: maximum flow and raw sound, for the track.

   Sound intensity, on a scale of 0 to 10

   1. 10/10Decat front section + Rog cat-back
   2. 9/10100-cell sports catalytic converter + Rog cat-back
   3. 8/10200-cell sports catalytic converter + Rog cat-back
   4. 7/10Rog cat-back only, factory catalytic converter retained
   5. 3/10Factory exhaust, for comparison

   Valves open. With the valves closed, every configuration becomes discreet again.

   Our advice. Your reference point is a score out of 10: 7 with the exhaust alone, 8 to 9 with the 200-cell sports catalytic converter, 10 with the decat version, for the track. With a remap by a tuner, it is also the front section that unlocks the power (see “Your vehicle”).

   

   What about the engine warning light? With a sports catalytic converter, it can come on with some engines: the sensor placed after the catalytic converter measures a different level of emissions control from the original. It is not a mechanical fault, and a remap by a tuner sorts it out. The decat version almost always triggers it. Passing inspection with a sports exhaust.

4. 4

   Step 4 of 5: Valves: our remote or your factory valves

   The valves set the volume at every moment: closed, the gases pass through the silencer and the car keeps a sound close to the factory one; open, they take the shortest route. All that remains is to choose who controls them.

   Rog system and remote

   Included

   

   The exhaust comes with our valves fitted and a two-button remote, open and closed; a small control unit fits in the boot. The valves stay in the position you choose, whatever the drive mode: open, they stay open; closed, they stay closed.

   Your factory valves

   Included

   • If your car has factory valves
   • Controlled by the drive modes

   If your car has factory valves, we deliver the exhaust with mounting points for them: your garage refits your valves there, and everything works as before, through the drive modes.

   

   Our advice. The remote if you want to decide for yourself, at any time; your factory valves if you value the standard drive modes. For inspection, present the car with the valves closed. On track, open them: that is where they come into their own.

   On the motorway, with the valves closed, all the exhaust flow passes through the silencer, designed for long distances: no drone at a steady speed. You open up when you feel like it, not when the motorway decides for you. Why our exhausts stay calm on the motorway.

5. 5

   Step 5 of 5: Looks: titanium colour and tips

   The last step, and the freest. The titanium colour and the tips are purely aesthetic choices: they change nothing about the sound or the performance of the exhaust. Choose them with your eyes.

   The titanium colour

   Three colours, at the same price: brushed, gold or purple. They only apply to titanium; in stainless steel, the exhaust keeps the colour of the steel.

   

   

   

   The tips

   Rog tips in chrome, gloss black or blued titanium, included in the price. You can also order the exhaust without tips.

   

   

   

Three set-ups, three uses.

If you are still unsure, start from how you use the car: here are the three set-ups we recommend most often for your car.

• Everyday

  • Stainless steel
  • Cat-back only
  • Rog remote

  Your car finds its voice, the factory emissions control stays in place, and you open the valves when you decide.

• Fast road

  • Titanium
  • 200-cell sports catalytic converter

  More sound and more breathing, with emissions control retained. With a remap, it is the basis of a Stage 2.

  View this configuration

• Track

  • Titanium
  • Decat

  For the track: maximum flow and raw sound. And on track, the valves stay open.
