HKS LEGAMAX Premium Cat-Back Exhaust – Mazda Roadster ND5RC (ND MX-5 Miata)

Elevate the exhaust note of your Mazda Roadster ND5RC with the HKS LEGAMAX Premium Cat-Back Exhaust — HKS's premium cat-back exhaust system engineered specifically for the Mazda Roadster ND5RC (ND MX-5 Miata with the 1.5L SkyActiv-G engine). The LEGAMAX Premium delivers a refined, sporty exhaust character that enhances the ND's naturally aspirated engine sound — more engaging and emotive than the factory exhaust without crossing into drone or excessive volume. Premium stainless steel construction throughout for long-term durability and a polished finish.

⚠️ Fitment Note – ND5RC Variant: This exhaust is engineered for the Mazda Roadster ND5RC — the ND MX-5 Miata with the 1.5L SkyActiv-G P5-VP engine, primarily the Japanese domestic market (JDM) specification. The North American ND MX-5 Miata uses the 2.0L SkyActiv-G engine (NDERC designation). Verify your specific ND Roadster/MX-5 variant, engine, and model year before ordering to ensure correct fitment.
