Racing Beat Power Pulse Muffler

Designed and manufactured by Racing Beat. 304 polished stainless steel muffler canister and all stainless construction, 2.375-inch tubing. The 3.5-inch OD exhaust tip is slightly oval in shape to provide a perfect balance and proportion for the Miata’s rear bumper. The 3.5" tip features subtle, bead-blasted Racing Beat logo. View a larger photo of this system, or view this system installed on a Miata.

The Power Pulse Muffler offers a deep, throaty exhaust note, without any harsh, buzzy or “droning” tones. All Racing Beat’s exhaust are “tuned” in to produce a modest exhaust tone at low speeds, and a bit more “attitude” under full throttle acceleration.

Connecting Pipe
Each Power Pulse Muffler requires the use of a Racing Beat connecting pipe section. We offer two (2) versions of this pipe: the Power Pulse Connecting Pipe, or the Sport Connecting Pipe.

The Power Pulse Connecting Pipe (year specific) incorporates a presilencer to moderate the sound level to deep, throaty tone. Both the muffler canister and the presilencer are manufactured using a stainless steel perforated tube core, wrapped with stainless steel wool, and packed to capacity with a high temperature ceramic wool. This design technique allows for a low restriction, straight through design, combined with superior sound dampening characteristics.

The Sport Connecting Pipe (year specific) is produced without the presilencer section, and offers a louder, and more robust exhaust note. While not obnoxious or buzzy, this pipe will allow the exhaust note to rise more moderately under acceleration.

Easy-to-install, this system can be bolted to the car in minutes using the supplied hardware kit. The muffler is “cat-back” emissions legal and meets all California sound level requirements.
