Exhaust side tuning - helping the RX-8 to exhale

The Racing Beat RX-8 Header for the Renesis engine is constructed using 100% stainless steel for superior quality, performance and appearance. Our exclusive cast stainless-steel mounting flange has been designed to allow the smooth transition of the exhaust gas flow from the engine to the primary tubing. Incorporated into the flange design are critical emission control air passages that were included on the OEM flange design. These small passages allow air to be pumped into the exhaust ports to aid in more efficient catalytic converter function. While this header is not considered "emissions legal" for street use, our header does not remove any catalytic converters, and is equipped with an oxygen sensor fitting and retains all emissions control functionality.

The Racing Beat RX-8 Header utilizes 1.75" OD, 14 gauge (.083"), mandrel-bent, 304 stainless steel tubing and features an exclusive Racing Beat engine-to-header flange. All required mounting hardware, an outlet gasket, and instructions are included. A engine-to-header gasket is NOT supplied with the kit, but the stock unit can be re-used unless it shows signs or damage, leakage, or extended wear.

As developed and tested on our engine dyno, the Racing Beat header produced a peak horsepower improvement of over 4 HP.

We are often asked about "heat wrapping" a header as a method to reduce heat in the engine bay. We do not recommend wrapping the header. Even though RX8 exhaust temperatures are not as high as other rotary applications, wrapping a stainless steel header will accelerate fatigue in the metal. A better answer is to use heat shields that do not reduce airflow around the header.

An engine-to-header gasket is available separately if needed. 

* Legal in California only for racing vehicles, which may never be used upon a highway.
