Here you will find everything that matters before configuring the exhaust for your Maserati GranTurismo / GranCabrio V6: catalytic converter, material, valves, tips and vehicle inspection.

The Maserati V6: Italian temperament, held in check by regulations
The V6 in your GranTurismo 2023 has noble blood: depending on the generation, it is either built in Maranello or derived from the MC20's Nettuno pre-chamber technology. Its temperament is real, its natural sound warm and brassy. But the factory exhaust, calibrated for discretion, holds back a significant part of it.
The Rog exhaust restores it: an assertive Italian timbre, an expressive climb, crackles on the overrun with the valves open, and prestige saloon discretion with the valves closed.
How the exhaust on your Maserati GranTurismo / GranCabrio V6 is put together
An exhaust system is best understood in two parts. Here is what each one does, and what Rog replaces.
The cat-back is the complete exhaust system
It is everything you can see under your Maserati GranTurismo / GranCabrio V6, from the outlet of the front section to the tips: pipes, silencers, 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 Maserati GranTurismo / GranCabrio V6, it is the downpipe, the pipe leading from the engine. It contains the factory catalytic converter: the second restriction in the exhaust, after the silencer. Replacing it is optional: it frees up the flow, and it is the ECU remap that turns that into horsepower.
The figures for your Maserati GranTurismo / GranCabrio V6
An exhaust system is judged first by ear and on the scales. The extra horsepower comes from an ECU remap.
Power
Torque
Published factory and Stage 2 figures.
The Rog exhaust works with or without an ECU remap. To get the full potential out of your Maserati GranTurismo / GranCabrio V6, we recommend taking it to an approved tuning centre afterwards.
To be completely transparent: the exhaust alone mainly improves breathing and sound. The significant gains come with Stage 2, the exhaust plus an ECU remap at an approved tuning centre, and Maserati's turbo V6 engines handle them with ease.
Configuring your exhaust, step by step
4 choices, in the same order as the product page configurator.
-
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
- 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.

Step 2 of 4: Front section: downpipe and catalytic converter
Optional: the downpipe on your Maserati GranTurismo / GranCabrio V6, with its 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
7/10Factory 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
8/10Road use and inspection
More flow, emissions control retained: the right option for road use.
100-cell sports catalytic converter
9/10Inspection: depends on local rules
More open than the 200-cell: the sound hardens at high revs and emissions control is reduced.
Decat
10/10Track use
Flow with no filter at all: the rawest sound and the sharpest response.
Sound intensity, on a scale of 0 to 10
- 10/10Decat downpipe + Rog cat-back
- 9/10100-cell sports catalytic converter + Rog cat-back
- 8/10200-cell sports catalytic converter + Rog cat-back
- 7/10Rog cat-back only, factory catalytic converter retained
- 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.
-
Step 3 of 4: Valves: Rog remote or factory control
Two ways to control the valves on your Maserati GranTurismo / GranCabrio V6.
Rog remote
A discreet control unit in the boot 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 silencer and stays composed when cruising; open, it makes itself heard when you choose. More about exhaust drone.

Step 4 of 4: Tips: the visual signature
Match the tips to the style of your Maserati GranTurismo / GranCabrio V6, understated or bold. A particular finish in mind? Send us a photo and we will look at it together.
- Chrome
- Gloss black
- Blued titanium
Your choices carry over to the product page: only the finishes, your VIN and the cart remain.
The Rog sound signature on the Maserati V6
Our exhaust frees the V6's Italian timbre: warm and brassy, expressive through the revs, with crisp crackles on the overrun with the valves open. With the valves closed, your Maserati regains the discretion of a prestige saloon. Temperament, on demand.

Every Maserati GranTurismo / GranCabrio V6 has its own story and its own use: if none of these profiles sounds like you, let's talk.
Maserati GranTurismo / GranCabrio V6: your questions
How much power does an exhaust system add to the Maserati GranTurismo / GranCabrio V6?
As standard, the Maserati GranTurismo / GranCabrio V6 produces 490 hp and 600 Nm. The exhaust alone acts first on sound, breathing and weight; the extra horsepower comes from an ECU remap. With a Stage 2 build, the published figures reach 560 hp and 690 Nm.
Stainless steel or titanium: which material for the Maserati GranTurismo / GranCabrio V6?
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 Maserati GranTurismo / GranCabrio V6?
It is not compulsory. The cat-back alone is enough to change the character of the Maserati GranTurismo / GranCabrio V6. Replacing the downpipe 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 Maserati GranTurismo / GranCabrio V6?
The cat-back only and the 200-cell converter both retain emissions control: present the Maserati GranTurismo / GranCabrio V6 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 Maserati GranTurismo / GranCabrio V6?
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 Maserati GranTurismo / GranCabrio V6.
What does a Rog exhaust cost for the Maserati GranTurismo / GranCabrio V6, 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.
