The MX-5 engine: the Jinba Ittai philosophy, right down to the exhaust
Your MX-5 NA follows Jinba Ittai, the unity of horse and rider: lightness, balance and total connection. In that philosophy, the sound is part of the experience, especially with the roof down. The discreet factory exhaust lets the little four-cylinder sing under its breath: it is the favorite upgrade of the worldwide MX-5 community.
The Rog exhaust gives it its full voice: a lively, mechanical timbre, an expressive climb, and light crackles on the overrun. With the roof down, the transformation is total, and the valves keep discreet journeys possible.
What makes up the exhaust on your Mazda MX-5 NA
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 the chassis of your Mazda MX-5 NA, from the outlet of the front section to the tips: pipes, muffler, 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 Mazda MX-5 NA, that is the part between the engine and the cat-back. It contains the factory catalytic converter: the second restriction in the exhaust, after the muffler. Replacing this part is optional: it frees up the flow, and an ECU remap is what turns that into power.
The figures for your Mazda MX-5 NA
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.

Torque
Published factory figures.
Our exhaust systems work perfectly with or without an ECU remap. On your Mazda MX-5 NA, however, we recommend having one done at an approved tuning center: that is what lets the engine reach its full potential.
Let's be honest: on an MX-5, nobody is looking for 100 extra horsepower, and the exhaust brings a moderate gain. What it really brings: better breathing, less weight, and a soundtrack that changes every journey. That is exactly the spirit of the car.
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 benchmark for high-end exhausts: tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.
Titanium
- 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 4: Front section: front pipe and catalytic converter
Optional: the front section of your Mazda MX-5 NA, 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
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
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
10/10Track use
No emissions control: maximum flow, raw sound, the sharpest revving.
Sound intensity, on a scale of 0 to 10
- 10/10Decat front section + 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 Mazda MX-5 NA.
Rog remote
A small control unit fits in the trunk. 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 highway, with the valves closed, the gases pass through the muffler, designed for cruising: no drone at a steady speed. You open up when you feel like it, not when the highway decides for you. More about exhaust drone.

Step 4 of 4: Tips: the visual signature
Match the tips to the style of your Mazda MX-5 NA, 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 MX-5
Our exhaust gives the MX-5 its full voice: a lively, mechanical timbre, an expressive climb, and light crackles on the overrun with the valves open. With the roof down, every journey becomes a celebration of Jinba Ittai. With the valves closed, the neighbors still love you.
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty.

Mazda MX-5 NA: your questions
How much power does an exhaust system add to the Mazda MX-5 NA?
From the factory, the Mazda MX-5 NA produces 115 hp and 148 Nm. An exhaust system on its own mainly changes the sound, the breathing and the weight; power is gained with an ECU remap. On a naturally aspirated engine, an ECU remap only brings a modest gain: what really changes is the sound and the response.
Stainless steel or titanium: which material for the Mazda MX-5 NA?
The Rog exhaust comes in stainless steel and titanium, at the price shown on the product page in your currency. 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 Mazda MX-5 NA?
No. On the Mazda MX-5 NA, the cat-back alone carries the valves and already transforms the sound. Replacing the front part is an option for going further: 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 Mazda MX-5 NA?
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 to the Mazda MX-5 NA?
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 does a Rog exhaust for the Mazda MX-5 NA cost, 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. Free delivery and a 3-year warranty.
