Developed for 01–05 Mazda MX5 / Miata Mk2.5 (NBFL) with the 1.6 engine (B6), this exhaust manifold uses application-specific runner geometry, sensor positions and a downstream connection matched to the vehicle.

Formed from 1.5-inch to 2.5-inch stainless steel pipework with TIG-welded joints, this manifold is designed to reduce restriction and support improved exhaust flow on naturally aspirated applications.
