Racing Beat 4:1 Stainless Steel Headers

Racing Beat offers a full line of exhaust headers for all 1990-2005 Miatas (non-turbo models). These headers are the results of extensive in-house R&D work by Jim Mederer, Racing Beat's co-founder and chief engineer. Our "4-into-1" style headers have been designed to combine the midrange power gains of the traditional "Tri-Y" style headers and the top end power gains typically associated with "4-into-1" style headers. Hundreds of combinations of tubing diameters, primary and secondary tubing lengths, collectors, and flange designs were tested during the development of these headers.

Manufactured entirely from 304-stainless steel for superior strength and durability, these headers are the first Racing Beat headers to feature our cast stainless-steel flange design.
