MBRP 2.5-Inch Axle-Back Exhaust System with Carbon Fiber Tips for 2016-2025 Mazda MX-5 Miata

The MBRP axle-back exhaust system. This single rear exit setup delivers a deep, aggressive race-inspired tone that stands out on the road or track, while improving exhaust flow for better throttle response and power delivery. Constructed from durable T304 stainless steel, it resists rust and corrosion for long-term reliability in various conditions.

With its mandrel-bent tubing and precision engineering, this system ensures seamless integration and consistent results that exceed basic replacements.
