Maserati MC20: unleashing the Nettuno, the complete guide
The MC20 marks Maserati's return to the top: a carbon mid-engined supercar with the pre-chamber Nettuno V6, Formula 1 technology approved for the road. A world first deserves a voice to match. This guide sets out, for your Maserati MC20 V6, what each choice changes: material, front section, sound, valves and fitting.

The MC20's Nettuno: pre-chamber Formula 1 technology, approved for the road
The Nettuno V6 in your MC20 is a world first: pre-chamber combustion derived from Formula 1, developed entirely by Maserati, with 630 hp from 3.0 litres, i.e. 210 hp per litre. It marks Modena's return to the top of engine technology. Its factory sound is technical and interesting, but type approval holds it back: the Nettuno has a higher register to reveal.
The ROG exhaust reveals it: a high-pitched, thoroughbred tone set free, full presence at high revs and crisp bangs on the overrun. The valves keep things civilised for low-key journeys.
What makes up the exhaust on your Maserati MC20 V6
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 MC20 V6, from the outlet of the front section to the tips: pipes, silencer, valves. This is where our research and development is focused, and it is what shapes the sound. On its own, it changes the character of the car.
The front section, where the catalytic converter sits
On your Maserati MC20 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 this part is optional: it frees up the flow, and an ECU remap is what turns that into power.
Your Maserati MC20 V6 in figures
On a modern car, an exhaust system first changes the voice, the breathing and the weight at the rear. Power, on the other hand, comes from an ECU remap.

Published factory and Stage 2 figures.
Our exhaust systems work perfectly with or without an ECU remap. On your Maserati MC20 V6, however, we recommend having it done at an approved tuning centre: it is what lets the engine reach its full potential.
In all transparency: the exhaust brings better breathing and a new dimension of sound. The Nettuno is designed with a considerable margin, but on a car of this level, every project deserves a dedicated discussion: call us before configuring.
Configuring your exhaust, step by step
3 choices, in the same order as the product page configurator.
-
Step 1 of 3: Material: stainless steel or titanium
For your Maserati MC20 V6, the exhaust costs €3,290 in stainless steel and €4,110 in titanium.
304 stainless steel
€3,290
- Weight
- Baseline
- Sound
- Full and rounded
The benchmark for high-end exhausts: tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.
Titanium
€4,110
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
Around 40% lighter than stainless steel for the same design, with a more metallic sound that turns crystal-clear at high revs. Its finish ranges from brushed to blued tints.
Over time, both hold up: 304 stainless steel stands up to winter salt and damp, and titanium does not rust. Stainless steel or titanium: what really changes.

Step 2 of 3: Front section: downpipe and catalytic converter
Optional: the downpipe on your Maserati MC20 V6, with its catalytic converter. Sound intensity is rated on our scale of 0 to 10, valves open; the factory exhaust scores 3.
Cat-back only
Included
7/10Factory emissions control
The factory catalytic converter stays in place. The starting point and, for many of our customers, more than enough.
200-cell sports catalytic converter
+€1,390
8/10Road use and inspection
Emissions control is still very much there, and flow improves noticeably. The choice for everyday driving.
100-cell sports catalytic converter
+€1,390
9/10Inspection: depends on local rules
Half as many cells: flow comes close to a decat and the sound gains real aggression at high revs.
Decat
+€1,070
10/10Track use
No emissions control: maximum flow, raw sound, the sharpest revving.
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? A sports catalytic converter can trigger it: the oxygen sensor after the catalytic converter detects less cleaning than with the factory unit. It is not a fault. An ECU remap recalibrates the sensor, and a session with a diagnostic tool clears the fault code. With a decat, the warning light is almost certain without a remap. If it happens to you, call us and we will point you in the right direction. Passing vehicle inspection with a sports exhaust.

Step 3 of 3: Valves: ROG remote or factory control
Two ways to control the valves on your Maserati MC20 V6.
ROG remote
A small control unit fits in the boot. Two buttons, open and closed: the valves respond at any moment, whatever the drive mode. Simple to fit, and we stay on hand throughout the installation.
Factory control
- Only for vehicles fitted with factory valves
- Controlled by the drive modes
If your vehicle is fitted with factory valves, the exhaust keeps their existing control. The drive modes decide, just as they did from the factory, with no added electronics.
On the motorway, with the valves closed, the gases pass through the silencer, designed for cruising: no drone at a steady speed. You open up when you feel like it, not when the motorway decides for you. More about exhaust drone.
The ROG sound signature on the Nettuno
Our exhaust reveals the Nettuno's full character: a high-pitched, technical tone, full presence at high revs and crisp bangs on the overrun with the valves open. A supercar from Modena should be heard: yours will be, whenever you decide.

Maserati MC20 V6: your questions
How much power does an exhaust add on the Maserati MC20 V6?
As standard, the Maserati MC20 V6 produces 630 hp and 730 Nm. An exhaust system on its own mainly changes the sound, the breathing and the weight; power is gained with an ECU remap. With a Stage 2 build, the published figures reach 700 hp and 820 Nm.
Stainless steel or titanium: which material for the Maserati MC20 V6?
For the Maserati MC20 V6, the ROG exhaust costs €3,290 in stainless steel and €4,110 in titanium. 304 stainless steel is tough, rounded in tone and the most popular choice; titanium is around 40% lighter for the same design, with a more metallic sound at high revs.
Do you need to replace the catalytic converter on the Maserati MC20 V6?
No. On the Maserati MC20 V6, the cat-back alone carries the valves and already transforms the sound. Replacing the downpipe is an option for going further: with a 200-cell sports catalytic converter for the road, 100-cell or decat for more radical use, with an ECU remap to turn it into power.
Will a ROG exhaust pass vehicle inspection on the Maserati MC20 V6?
With the cat-back only or the 200-cell sports catalytic converter, emissions control is retained: present the car with the valves closed. The 100-cell brings more sound and flow, and whether it is accepted at the emissions test depends on the car and local rules; the decat version is intended for track use.
How is the ROG exhaust fitted on the Maserati MC20 V6?
No welding or cutting, using clamps and gaskets. Allow two hours on average for a well-equipped mechanic. The exhaust is built for your VIN, which guarantees compatibility before it ships.
What price and lead time for a ROG exhaust on the Maserati MC20 V6?
From €3,290 to €5,500 depending on the configuration. Allow 20 working days from order confirmation to delivery. Free delivery and a 3-year warranty.
Unsure about your configuration? Give us a call.
Stainless steel or titanium, cat-back only or the complete system: the right choice depends on how you drive and on your Maserati MC20 V6. We take the time to talk it through before you order, with a reply within 24 hours. We are not here to sell to you over the phone: we help you choose, even if that means a cheaper option because it suits the way you drive.
RogMotorsport is a French brand built on one conviction: with an exhaust system, the support matters as much as the product. More than 500 exhaust systems fitted and a rating of 4.9 out of 5.
