Exhaust Mazda MX-5 (1989-1998)

For Mazda MX-5 models (NA 1989-1997, NC 2005-2015, ND 2015+), the common aftermarket exhausts are mainly cat-back systems. These start from the secondary catalytic converter and extend towards the rear. They are often made from premium stainless steel (T304) and feature a typical diameter of 63.5 mm (2.5").

Upgrading to a premium exhaust system for your Mazda MX-5 offers several advantages:

• Sound Enhancement: Produces a sportier, rougher sound especially noticeable between 1500-2200 rpm and dynamic performance at higher rpms without excessive cabin noise.
• Performance Gains: Improved torque and power, with independent tests showing up to +7.4 lb-ft of torque increase.
• Aesthetic Appeal: Features like polished, double angled exhaust tips that enhance rear appearance.
• Easy Installation: Most systems provide a plug & play experience with supplied gaskets and hardware.
• Durability: Constructed with T304 stainless steel, mandrel bent piping, and TIG welding for long-lasting quality.

These enhancements provide an overall better driving experience on your Mazda MX-5.

Premium Mazda MX-5 exhausts commonly use T304 stainless steel for several reasons:

• Excellent corrosion resistance for longer lifecycle.
• Mandrel bent piping ensures smooth airflow for optimal performance.
• TIG welding provides durable, high-quality joints.
• Premium surface finishes such as polished or ceramic coated tips to improve aesthetics and heat resistance.

Using these high-grade materials ensures both durability and improved vehicle sound and performance reliability.

Aftermarket exhaust systems for the Mazda MX-5 typically produce a louder, more aggressive sound compared to the stock exhaust, but are designed to avoid excessive cabin noise:

• Sound usually peaks around 88 dB inside the cabin for sporty models, which is dynamic yet not overly loud.
• The sound is characterized as a deeper, rougher roar that enhances the race-inspired driving feel.
• Some systems also offer optional DE-CAT setups (removal of rear catalytic converter) for even more aggressive sound and track use, though not legal for public roads.

These exhausts are engineered to balance street legality, sound enjoyment, and performance gains for daily and spirited driving.

Legality depends on the specific exhaust system and local regulations:

• Some exhausts come with official CE and E24-103R certifications ensuring compliance with European emission and noise laws.
• Others are sold as non-homologated performance parts and may not be legal for road use in all regions.
• Removal or modification of catalytic converters (DE-CAT) is typically illegal on public roads in many countries.
• Users should check local laws and ensure any exhaust installed complies with noise and emissions regulations in their location.

Krosfou offers high-quality, compliant parts for pollution control, maintaining legal standards for road vehicles.

Most Mazda MX-5 performance cat-back exhausts are designed for straightforward installation:

• They install without major modifications, often fitting directly onto existing mounting points and piping.
• Installation time can be as short as 15 minutes for some models.
• Gaskets and fasteners are usually included to ensure a proper seal, though sometimes bolts or studs may need reuse or separate sourcing.
• Plug & play design allows for easy upgrades with minimal tools and mechanical experience.

Still, professional installation is recommended to ensure correct fit and maintain vehicle warranty and performance.

Installing a quality aftermarket exhaust on your Mazda MX-5 can yield these benefits:

• Increase in low to mid-range torque, typically around +7.4 lb-ft depending on system and engine.
• Better exhaust flow reduces back pressure, improving engine efficiency and responsiveness.
• Potential slight horsepower gains that improve acceleration and throttle response.
• Reduced weight compared to some stock exhaust configurations due to stainless steel construction.

These upgrades contribute to a more engaging and enjoyable driving experience for your MX-5.
