The Racing Beat Manifold for the 2001-2005 MX-5 NBFL is the result of extensive research and development efforts, both on the dynamometer and on the road. This manifold includes a tuned 4-in-1 configuration that optimizes flow characteristics and performance.
Hundreds of development hours and more than 200 test stands have been invested by Racing Beat in the refinement of the manifold. As a result, this now offers measurable increases in power and torque over the entire speed range.
To ensure the longevity of the 4-in-1 manifold, it is made exclusively from 304 stainless steel. The stainless steel cast engine-to-manifold flange has specially designed exhaust ports that smoothly transition to each primary pipe.
The 1.7 inch diameter primary tubes collect in a 2.375 inch diameter secondary pipe. At the same time, all emission-reducing devices are retained.
