The Racing Beat Miata Race Exhaust is a lightweight catback exhaust system that is intended for racing applications. Designed to meet the demands of the Miata autocross/circuit racers, this system is significantly lighter than the Power Pulse exhaust system and has been designed to meet a race track-imposed sound limit.
Produced in Racing Beat's California manufacturing facility, the Miata Race Exhaust features a light weight 304-stainless steel muffler canister, inlet and outlet tubing, single-wall tip (with etched Racing Beat logo), attachment hangers, and connecting flange. The muffler canister utilized features a straight-through design for optimum exhaust gas flow and includes a combination of stainless steel and high-temperature ceramic wool packing material for sound absorption.
In keeping with the emphasis on the lightweight aspect, Racing Beat adopted a unique approach to the development of the extensive hanger assemblies that were required for this muffler; we used lighter 5/16” OD rod material for the lengthy hanger assemblies, and designed a unique ½” OD forged end hanger, which we then mated to the outlet end of each hanger assembly. The design of this hanger end ensures a secure "no slip" attachment with the stock rubber muffler hangers to prevent lateral movement of the exhaust during hard cornering.
Power Pulse Muffler:
1990-97 Miata Single tip: 18 lbs
1990-97 Miata Race: 11.25 lbs
Connecting pipe (without presilencer) 6.5 lbs
In combination with the Sport connecting pipe, the complete Miata Race Exhaust system will weigh under 18 lbs.
Racing Beat Final Notes
This is the lightest exhaust system we offer for the 96-97 Miata and suited perfectly for the weight conscious racer where every ounce counts. This is not a "touring exhaust" and may not appeal to more conservative drivers and/or passengers.
