Porsche 911 Carrera 997.1 and 997.2: the matured flat-six, the exhaust system guide

With the 997.1 and 997.2, the 911 Carrera went back to round headlights and a silhouette true to its lineage. The 997.1 from 2004 to 2008 keeps a 325 hp naturally aspirated flat-six; the 997.2 from 2008 to 2012 adopts direct injection and rises to 345 hp. Two engines with a superb voice, which the factory exhaust takes pains to keep discreet. The same Rog valved exhaust fits both; this guide walks you through each option.

Your valved exhaust for Porsche 911 Carrera 997.1 is configured from your VIN, and the Porsche 911 997 Valved Exhaust page brings together every system we make for this generation.

The naturally aspirated flat-six of the 911 Carrera 997.1 and 997.2

The 911 Carrera 997.1 keeps the water-cooled, naturally aspirated flat-six, mounted behind the rear axle: 325 hp and 370 Nm. On the 997.2, Porsche reworked this engine in depth, with direct injection, to reach 345 hp and 390 Nm and an even sharper response. In both cases, the flat-six revs with a linearity that invites you to chase the top of the rev counter.

Despite this change of engine generation, the body stays the same from one phase to the next, hence a shared Rog exhaust. On a naturally aspirated flat-six, the sound changes register as the revs climb, and the factory exhaust smooths out its nuances. The Rog exhaust gives them back to you whenever you decide, while keeping a 911 that is usable every day, without touching the engine or the ECU.

How the exhaust on your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2 is put together

An exhaust system is best understood in two parts. Here is what each one does, and what Rog replaces.

How the exhaust system is laid out From left to right: the engine, the front section, then the Rog cat-back with its valved muffler and tips.Front sectionRog cat-back: the complete exhaustEngine
Valves closed: the muffler does its work and the sound stays discreet.Valves open: the direct path opens up and the engine finds its full voice.Schematic only; the actual routing depends on the vehicle.

The cat-back is the complete exhaust system

It is everything you can see under your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, from the outlet of the front section to the tips: pipes, mufflers, valves. This is the part where most of our research and development goes: it is what shapes the sound, and it is enough on its own to transform the car.

The front section, where the catalytic converter sits

On your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, it is the front pipes, just after the manifolds. They contain the factory catalytic converter: the second restriction in the exhaust, after the muffler. Replacing it is optional: it frees up the flow, and it is the ECU remap that turns that into horsepower.

The figures for your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2

An exhaust system is judged first by ear and on the scales. The extra horsepower comes from an ECU remap.

The Rog exhaust works with or without an ECU remap. To get the full potential out of your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, we recommend taking it to an approved tuning centre afterwards.

Being naturally aspirated, this flat-six leaves little headroom for remapping: at Stage 2, the 997.1 is quoted at 357 hp and 415 Nm and the 997.2 at 378 hp and 436 Nm, thanks to mapping work rather than forced induction. The Rog exhaust takes credit for none of these gains; it is their audible extension.

Configuring your exhaust, step by step

4 choices, in the same order as the product page configurator.

  1. Step 1 of 4: Material: stainless steel or titanium

    Titanium costs more than stainless steel; the price of each version is shown on the product page, in your currency.

    304 stainless steel

    Baseline

    Weight
    Baseline
    Sound
    Full and rounded

    The safe bet: strong, corrosion-proof, with a full, rounded sound. The best value for money.

    Titanium

    Weight
    Around 40% lighter
    Sound
    Metallic, crystal-clear

    It makes the exhaust around 40% lighter for the same design. Its note is more metallic and clearer higher up the rev range, and its finish ranges from brushed to blued.

    No worries on durability: 304 stainless steel shrugs off winter road salt and titanium does not rust. Stainless steel or titanium: what really changes.

  2. Step 2 of 4: Front section: front pipes and catalytic converter

    Optional: the front pipes on your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, with their catalytic converter. Each option is placed on our sound scale of 0 to 10, valves open, with the factory exhaust at 3.

    Cat-back only

    Included

    7/10

    Factory emissions control

    The factory front section stays in place. It is already a complete transformation, and the choice of many of our customers.

    200-cell sports catalytic converter

    8/10

    Road use and inspection

    More flow, emissions control retained: the right option for road use.

    100-cell sports catalytic converter

    9/10

    Inspection: depends on local rules

    More open than the 200-cell: the sound hardens at high revs and emissions control is reduced.

    Decat

    10/10

    Track use

    Flow with no filter at all: the rawest sound and the sharpest response.

    Sound intensity, on a scale of 0 to 10

    1. 10/10Decat front pipes + 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.

    What about the engine warning light? With a sports cat, 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 failure, but a warning light should never be masked or cleared without dealing with its cause: the right answer is a catalytic converter suited to the engine, with a map by a tuner who takes it into account. The decat version, for track use only, almost always triggers it. If this happens to you, write to us and we will point you in the right direction. Passing vehicle inspection with a sports exhaust.

  3. Step 3 of 4: Valves: Rog remote or factory control

    Two ways to control the valves on your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2.

    Rog remote

    Rog remote for opening and closing the valves

    A discreet control unit in the trunk and a two-button remote: you open and close whenever you like, independently of the drive modes. For fitting, we support you by email.

    Factory control

    • Only for vehicles fitted with factory valves
    • Controlled by the drive modes

    For vehicles fitted with factory valves: the exhaust connects to their control and the drive modes stay in charge, with no extra control unit.

    At 130 km/h, many sports exhausts drone. Here, with the valves closed, the exhaust flows through the muffler and stays composed when cruising; open, it makes itself heard when you choose. More about exhaust drone.

  4. Step 4 of 4: Tips: the visual signature

    Match the tips to the style of your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, understated or bold. A particular finish in mind? Send us a photo and we will look at it together.

The Rog sound signature on the flat-six of the 911 Carrera 997.1 and 997.2

The 911 Carrera's flat-six has a unique voice: a muffled, metallic rumble at idle, then an ever higher-pitched howl as the revs climb. Behind the factory exhaust of the 997.1 and 997.2, this progression remains perceptible but very polished, to the point of erasing what gives a naturally aspirated 911 its charm.

With the valves open, the Rog exhaust unfolds the full range of the flat-six: a grainy idle, a clean and continuous climb, a metallic howl high in the revs, gear after gear. With the valves closed, your 911 regains the discretion of a grand tourer, in town and on the highway alike.

Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2: your questions

How much power does an exhaust system add to the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2?

As standard, the Porsche 911 Carrera type 997.1 produces 325 hp; the Porsche 911 Carrera type 997.2 produces 345 hp. The exhaust alone acts first on sound, breathing and weight; the extra horsepower comes from an ECU remap. The published Stage 2 figures for each model are shown in the figures table.

Stainless steel or titanium: which material for the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2?

The Rog exhaust comes in stainless steel and titanium, at the price shown on the product page in your currency. Stainless steel is the safe bet, with a full sound; titanium makes the exhaust around 40% lighter and gives a more metallic note higher up the rev range.

Do you need to replace the catalytic converter on the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2?

It is not compulsory. The cat-back alone is enough to change the character of the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2. Replacing the front pipes is how you go further, together with an ECU remap: 200 cells for the road, 100 cells or decat for more radical use.

Will a Rog exhaust pass vehicle inspection on the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2?

The cat-back only and the 200-cell converter both retain emissions control: present the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2 with the valves closed. With the 100-cell, acceptance at the emissions test depends on the car and local rules; the decat is intended for track use.

How is the Rog exhaust fitted to the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2?

With clamps and gaskets, no welding or cutting: around two hours in the workshop for a well-equipped mechanic. The exhaust is built to the VIN of your Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2.

What does a Rog exhaust cost for the Porsche 911 Carrera type 997.1 or 911 Carrera type 997.2, and how long does it take?

The price depends on the configuration and is shown on the product page, in your currency. Allow 20 working days from order confirmation to delivery. Delivery is free and the exhaust comes with a 3-year warranty.
