Our favorite Miata header for normally aspirated Miatas, consistently outperforms the Jackson Header and for less money.

Manufactured entirely from 304-stainless steel for superior durability, this 4:1 Miata header is sure to offer many years of enthusiastic Miata performance driving.

Over 200 on-chassis dyno runs allowed Racing Beat to determine the optimum tubing diameter and lengths for both the primary and secondary tubes. Racing Beat also took the opportunity to experiment with various engine-to-header flange porting configurations and collector designs specifically on the Miata application.

This development allowed Racing Beat to fine-tune the performance of this header to achieve performance that is superior to stock at all points of the RPM range. Racing Beat's exclusive cast, stainless steel engine-to-header flange features specially designed exhaust ports that transition smoothly to the primary tubing. Large diameter 1.5" OD tubing has been used for the primary tubing, and then collects into the 2.0" OD secondary.

But, does NOT fit with many Miata supercharger setups. So, get this Miata header if you do not plan to add a supercharger to your Miata.

Note that adding any header makes a slight increase in the exhaust sound level on your Miata. Note that latest version of this Racing Beat Miata Header has a small factory installed dent for clearance to the Miata steering assembly.

NOT CARB LEGAL IN CALIFORNIA (can be used in off road vehicles only).
