Designed around 97–98 Mazda MX5 / Miata / Eunos Roadster Mk1 (NA) with the 1.8 engine (BP), this equal-length tubular manifold uses closely matched runner lengths for balanced exhaust pulses at the collector.
The manifold uses 1.75-inch to 2.5-inch stainless steel pipework with TIG-welded joints; its runner and collector layout is designed to improve exhaust flow and support sharper engine response.

Developed for the Mazda MX-5 NA
The original MX-5 is defined by low weight, direct controls and a responsive
naturally aspirated engine. Exhaust upgrades for the NA should complement that
character with clean response and an engaging tone without masking the car’s
simplicity. Check the product-specific engine, model-year and fitment details above,
as 1.6 and 1.8-litre applications are not always interchangeable.
