The heart of our Racing Beat Power Pulse muffler for the 2004-05 Mazdaspeed Miata is our polished 304-stainless steel canister. The inlet and outlet tubes also feature mandrel-bent 304-stainless steel for excellent durability and appearance. For maximum performance potential, our muffler features the same 2.375" OD Straight-Flow internal design configuration as our RX-7 Turbo II exhaust systems. Finished with a 3.5-inch polished 304-stainless steel tip, this large diameter muffler will handle applications from stock to race.

Designed entirely by Racing Beat, this muffler features stainless steel wool and ceramic sound-deadening packing insulation to provide the optimum exhaust note for your Miata. The Power Pulse Muffler for all Miatas offers a deep, throaty exhaust note without any harsh, buzzy or droning tones. All Racing Beat's exhaust are tuned in-house by our engineering staff to produce a modest exhaust tone at low speeds, and a bit more "attitude" under full throttle acceleration.

Although the non-turbo muffler we offer will fit onto the Mazdaspeed version, we felt the sound level output was just too quiet. (Since the exhaust on this application passes through the turbo, a catalytic converter, a presilencer AND a muffler, the final exhaust tone is very quiet on the stock application. Even with the rear muffler completely OFF the car, the sound level is still fairly quiet.) The design of this Mazdaspeed-version muffler is identical to our standard non-turbo version, but we have modified the internal specifications to allow the exhaust tone to produce a slightly more aggressive tone.

On an otherwise stock 1999 Miata (baseline hp - 110.6) our dyno tests have shown a 2.4 hp gain (max hp - 113.0) with the addition of this muffler. Combine this muffler with a Racing Beat air intake for gains of up to 8.5 hp! Don't be swayed by exaggerated performance claims made by other aftermarket suppliers - big HP gains from an aftermarket rear muffler simply don't exist. If they did, why would Mazda leave this untapped horsepower behind?

Each Power Pulse muffler is supplied with a replacement OEM donut style gasket. Installation can be completed using basic hand tools; simply unbolt the two retaining nuts, slip the original muffler off the rubber hanger grommets, and then reverse the process for installation of the new Power Pulse muffler. The Power Pulse muffler is 50-state emissions legal and meets all California sound level requirements.
