Designed and manufactured by Racing Beat, this high-flow silencer is intended for all 1990-2005 MX-5's. The heart of our Power Pulse Exhaust System is our 304 polished stainless steel muffler canister. This polished canister is equipped with stainless steel inlet and outlet pipes for superior durability. The Power Pulse Silencer features the same 2.375-inch Straight-Flow internal design configuration as our RX-7 Turbo II exhaust systems. The 3.5-inch OD exhaust tip is manufactured using highly polished 304-stainless steel and is slightly oval in shape to provide a perfect balance and proportion for the MX's rear bumper. Each tip features a subtle, bead-blasted Racing Beat logo to add the finishing touch! Select these links to view asy larger photo of this system, or to view this system installed on a MX-5
Designed entirely by Racing Beat, this muffler features a combination of stainless steel and ceramic sound-deadening insulation to provide the optimum exhaust note for your MX-5. The Power Pulse Silencer 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 team to produce a modest exhaust tone at low speeds, and a bit more “attitude” under full throttle acceleration.
As reviewed in the November 1999 issue of Import Tuner, this Power Pulse exhaust system (muffler and connecting pipe) added 3.2 horsepower to the wheels of a 1990 Miata. Combine this exhaust with a Racing Beat High Flow Air Intake for gains of up to 9 hp!
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.
Note: This silencer must be used with a Connecting Pipe (select the year for your application) for correct fitment.
