Note: This muffler is compatible with the Racing Beat mid-pipe we offer HOWEVER no catalytic convertor is included - you will likely need to build a catalytic convertor section to connect between your headers (either Racing beat or stock) and the midpipe/muffler.
Designed and manufactured by Racing Beat, our Power Pulse Muffler is intended for use on all 1990-1997 Miatas. The heart of our Power Pulse Exhaust System is our polished 304-stainless steel muffler canister. This polished canister is equipped with stainless steel inlet and outlet pipes for superior durability. For maximum performance the Power Pulse Muffler 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 entirely by Racing Beat, this muffler features a internal combination of stainless steel wool and ceramic sound-deadening packing insulation to provide the optimum exhaust note for your 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-house by our engineering team to produce a modest exhaust tone at low speeds, and a bit more "attitude" under full throttle acceleration.
Easy-to-install, this muffler can be bolted to the Racing Beat Connecting Pipe in minutes using the supplied hardware kit. The muffler is "cat-back" emissions legal and meets all California sound level requirements.
Performance
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!
