MX-5 Cat-Backs

Upgrade your exhaust setup with a high-performance MX-5 cat-back system from BOFI Racing. Our range is designed to fit directly to your existing catalytic converter, offering a variety of options for NA, NB, NC and ND models. Whether you’re looking for a refined sound or something more aggressive, we have the perfect cat-back solution to suit your build.

Choosing between resonated and non-resonated cat-back exhausts comes down to the sound and driving experience you’re after. A resonated exhaust will give you a refined, quieter tone — reducing unwanted droning at cruising speeds. If you have a daily commute, or simply want a more tasteful exhaust note, this option offers a performance boost without being too loud.

On the other hand, a non-resonated exhaust delivers a raw, aggressive sound that’s sure to turn heads. With no resonator to muffle the noise, you’ll enjoy a more race-inspired exhaust note, which is ideal for enthusiasts looking for maximum sound and performance, especially on the track.

About our range of MX-5 Cat-Back Systems

Whether you’re looking to change the tone of your MX-5, or just wanting to improve performance with a more efficient exhaust flow — our selection of MX-5 cat-back systems has you covered. We offer resonated and non-resonated options, providing everything from a quiet, street-friendly note to a more raw, race-inspired sound.

The Cobra Sport 2.5-inch Resonated cat-back exhaustis for the Mazda MX-5 ND, perfect for owners who want a smooth but bold sound. As with most Cobra exhausts, you can personalise your setup by choosing between inverted or rolled exhaust tips for that perfect finishing touch. For MX-5 ND drivers who want something more punchy, this Cobra cat-back exhaust is non-resonated, giving the exhaust a bigger growl. While it’ll also be slightly lower in volume, resonators take certain tones out of the exhaust note — giving it a smoother sound overall.

To fit this exhaust, you’ll need the Cobra Sport rear diffuser for the MX-5 ND.

Frequently Asked Questions

What are the main benefits of installing an aftermarket MX-5 cat-back system?

A cat-back exhaust system will not only change the sound of your Mazda MX-5, but also improve exhaust flow. This can lead to noticeable gains in horsepower and torque, especially for forced induction setups. Additionally, it provides a more engaging and dynamic driving experience.

How easy are aftermarket cat-back systems to install?

Our cat-back systems are designed for easy installation, connecting directly to your existing catalytic converter with minimal hassle. If your MX-5 has a stock exhaust, most cat-back systems are bolt-on kits, meaning they can be installed with basic tools and don’t require any welding or major modifications. Some systems may require adjustments or minor fitment tweaks, though, particularly if your car has other aftermarket components.
