Manifold, exhaust, stainless steel, Racing Beat Performance

Manufactured entirely from 304-stainless steel to provide both outstanding durability and appearance, the Racing Beat 4-to-1 configured header is sure to offer the MX-5 owner many years of performance. Their exclusive, cast stainless-steel engine-to-header flange features specially designed exhaust ports that transition smoothly to the primary tubing. Large diameter 1.7" O.D. tubing has been used for the primary tubing, collecting into a specially configured collector assembly. Exhaust gas exits the header through an OEM stainless-steel rear flange, mating to the factory connecting pipe section.

Each header kit comes complete with detailed installation instructions and a plug-in OEM style electrical extension wire for the relocation of the secondary oxygen sensor. The stock engine-to-header gasket can be reused if there are no visible signs of distress or wear. (Mazda uses a heavy duty metal gasket that can be reused several times.)

Note: This performance manifold is designed for racing as doesn't have a catalytic converter. On the original system the catalytic converter is combined with the manifold so by installing this manifold you are de-catting your exhaust system.
