Racing Beat Sport/Race: 83 db (3000 RPM - static), 93 db (5000 RPM - Static)
Stock Muffler: 81 db (3000 RPM - static), 92 db (5000 RPM - Static) 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.Įxtensive testing and evaluation produced the following comparative results:
As an alternative, 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 ½” OD hangers on the stock MX-5 muffler posed an interesting challenge, if we used ½” OD hanger rod material for the Racing Beat hangers, these hanger assemblies would prove to be unnecessarily heavy. In keeping with the emphasis on the lightweight aspect of the MX-5 ND design principles, Racing Beat adopted a unique approach to the development of the extensive hanger assemblies that were required for this muffler. This is a 33% reduction in weight over the stock system! The stock mounting studs and retaining springs are retained for use with Racing Beat exhaust. Racing Beat incorporated a Mazda-OE mounting flange on the inlet end of the exhaust to securely capture, retain and seal the stock donut-shaped swivel gasket. 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. Produced in Racing Beat's California manufacturing facility, the Sport/Race Exhaust features a MX-5-designed 304-stainless steel muffler canister, inlet and outlet tubing, single-wall tip (with etched Racing Beat logo), attachment hangers, and connecting flange. Yes, we could have just made one muffler both Brembo and non-Brembo ND's but why offer a compromise? Each version deserves a perfectly fitted muffler tip, and that's what we offer! True to the ideals of racing principles, we've stripped this exhaust down to only the most critical elements in an attempt to strip away unwanted excess weight.īrembo Note: During the fitting of the exhaust to the Brembo-equipped ND we noted the the rear diffuser on this vehicle package required a slight reposition to correctly position the exhaust tipe within the cut-out opening. are needed to unleash or dampen the character of the Racing Beat Sport/Race Exhaust this exhaust will appeal to the true MX-5 motoring enthusiast.
