A true Miata classic for over 25 years! Designed and manufactured by Racing Beat, our extremely popular Power Pulse Miata Exhaust System is intended for use on all 1990-95 Miatas. This complete cat-back, bolt-on system is easy-to-install and includes all required mounting hardware. The Power Pulse Miata Exhaust System is 50-state emissions legal and meets all California sound level requirements.
Power Pulse Muffler
The heart of our Power Pulse Miata Exhaust System is our polished 304-stainless steel muffler canister. This polished canister is equipped with stainless steel inlet and outlet pipes which provides superior durability and a stunning appearance. For maximum performance the Power Pulse Miata Exhaust System features the same 2.375" OD Straight-Flow internal design configuration as our RX-7 Turbo II exhaust systems. The 3.5" OD exhaust tip is manufactured using highly polished 304-stainless steel and is slightly oval in shape to provide a perfect balance and proportional look for the Miata's rear bumper. Each tip features a etched Racing Beat logo to add the finishing touch!
Designed, tested, and assembled in the USA by Racing Beat, this Miata muffler features an internal combination of stainless steel wool and ceramic sound-deadening packing insulation to provide the optimum exhaust note for your Miata. The Power Pulse Miata Exhaust System offers a deep, throaty exhaust note, without any harsh, buzzy or "droning" tones. All Racing Beat's exhaust systems 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.
Power Pulse Connecting Pipe
The Power Pulse Connecting Pipe incorporates a presilencer unit to further moderate the sound level to a 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.
If you prefer a louder, more sporty exhaust note, we also offer the Power Pulse Exhaust System with a Sport Connecting Pipe (without presilencer). While not obnoxious or buzzy, this sport pipe will allow the exhaust note to rise moderately under acceleration.
As reviewed in the November 1999 issue of Import Tuner Magazine, this Power Pulse Miata exhaust system (muffler and connecting pipe) added 3.5+ horsepower to the wheels of a 1990 Miata. After repeated dyno testing sessions and years of consumer feedback, we're comfortable stating that this is the maximum average peak HP performance gain you'll find from a streetable, straight-through (noise level legal) aftermarket Miata exhaust system.
We're proud to see that our Miata exhaust systems have proven to be so popular after all these years! We attempted to set a benchmark for sound and performance levels early-on with our Miata exhaust systems as the result of extensive dyno testing, on-road evaluation, and sound level testing. Our goal of course was to maximize performance while developing an exhaust tone that appealed to the the broadest range of Miata enthusiasts - not too loud, not too quiet. Although the Miata was introduced in the era of then booming Japanese sport compact market, we were challenged to develop an exhaust system that didn't sound like the mass-producted "import racer" exhaust systems that were flooding the import market at the time. While most of these extreme and harsh sounding rocket racer exhausts are long gone (as well as most of the cars they were installed onto)... Racing Beat exhaust systems for the long-lasting and classic Miata are still as popular as ever.
All Racing Beat exhaust systems for the Miata are assembled in-house by Racing Beat using the same welding jigs that were developed many years ago. You can be assured that every Miata muffler or connecting pipe section is virtually that same as a component produced years and years ago. No fitting issues, no misalignment, no installation hassles, just a trouble-free do-it-yourself effort.
