MX-5 Racing Beat Race Manifold for manual and auto transmission
MX-5 Racing Beat Race Header (MT & AT Models) – Upgrading your exhaust system with a high efficiency exhaust header is a time-proven method to improve the gas flow from your engine. Although modern exhaust manifolds have improved dramatically over the years, and may in fact resemble a traditional header in shape, testing has proven that performance improvements can be obtained with continued refinement of the exhaust manifold design. While the automotive aftermarket might we focusing their efforts solely on performance improvements, the OE manufacturers must combine performance, emissions, sound level limitations, and extended durability factors in their designs. While these parameters are also of concern to the aftermarket, our primary focus directed to maximizing performance.
Manufactured entirely from 304-stainless steel to provide both outstanding durability and a stunning appearance, the Racing Beat 4-to-1 configured header is designed to offer the MX-5 owner noticeable performance gains. Our exclusive, cast stainless-steel engine-to-header flange features specially designed exhaust ports that transition smoothly to the primary tubing. Large diameter 1.7" OD tubing has been used for the primary tubing, collecting into a specially configured collector assembly. Exhaust gas exits the header through an genuine Mazda OEM stainless-steel rear flange, mating to the factory connecting pipe section.
  
Emissions:- The secondary catalytic converter incorporated into the mid-pipe section (aft of the header section) is retained. Since a factory-placed catalytic converter is being removed by the install of this component, this race header is NOT considered emissions legal for street use. Both primary and secondary oxygen sensors are retained and are relocated into the header outlet collector. (Although this configuration will not affect engine performance, it is possible that this configuration will trigger an error code with the OBDII system and illuminate the “check engine light” on the vehicle.) To avoid this from occurring, we offer an optional Race Header Wiring Kit that relocates the secondary oxygen sensor.
Installation:-Each header kit comes complete with detailed installation instructions
