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.
