The Racing Beat Power Pulse Exhaust for the MX-5 ND offers an exciting opportunity to experience the joys of the classic open-air driving experience. For over 25 years Racing Beat has been developing sport-tuned exhaust systems for the Miata/MX-5 application.
Produced in Racing Beat's California manufacturing facility, the Power Pulse Exhaust features a MX-5 designed crimped-edge 304-stainless steel muffler canister, stainless steel inlet and outlet tubing, dual single-wall stainless steel tips with etched Racing Beat logos, hangers, and connecting flange. The muffler canister utilized features a straight-through split-Y internal design for optimum exhaust gas flow and includes a combination of stainless steel and high-temperature ceramic wool packing material for sound absorption. Racing Beat incorporates 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 stock mounting studs and retaining springs are retained for use with Racing Beat exhaust.

On the Road:
Like all of Racing Beat's Miata Power Pulse Exhaust systems, this provides a modest increase in exhaust tone with minimized annoying or harsh tones. As compared with the relatively quiet stock exhaust system, the Racing Beat exhaust provides a more open and throaty exhaust tone throughout the entire RPM range - most notable in the lower RPM range. Racing Beat notes that the increased exhaust note is most pronounced during acceleration, increasing in volume at higher RPMs and engine load, however low RPM frequencies can be more pronounced in the 2000-1500 RPM range (especially noted in 2nd gear "parking lot" deceleration).
