Racing Beat Dual Tip Muffler (1990-1997)
Applications Mazda Miata
Part Number 56466

The dual tip muffler project was originally designed for a 2001 project Miata for Mazda USA. Reaction was very positive and work was started on the development of Power Pulse Dual Tip Mufflers for all Miata applications. To view a larger photo of this system on a Miata, click here.

The Racing Beat Dual Tip Muffler is produced entirely from 304 stainless steel for superior durability and appearance. The inlet tube features a thick, cast-stainless steel flange that provides excellent gas sealing capabilities. Additional strengthening for the inlet and outlet tubes is provided by stainless steel supporting gussets and hanger support rods. Each stainless steel outlet tube feeds into a double-walled tip for an aggressive and sporty look. The two 3.5-inch exhaust tips are manufactured using highly polished 304-stainless steel and are slightly oval in shape to provide a perfect balance and proportion with the Miata’s rear bumper. Each tip features a subtle, bead-blasted Racing Beat logo to add the finishing touch!

Like all Racing Beat exhaust components, this system has been “tuned” to provide the Miata with a deep, throaty exhaust note, without any harsh, buzzy or “raspy” sounds. When combined with a Racing Beat connecting pipe and presilencer combination, this dual tip exhaust system will add just the right amount of “attitude” to your Miata!

Each system comes complete with fully detailed instructions and mounting hardware, and can be easily installed by the weekend mechanic using only simple hand tools. A positioning template is provided to assist with cutting of the new opening for the additional outlet tip. The new opening can be cut through the soft urethane bumper material using only a small utility knife. A small sanding block is then required to “smooth” out the opening to the final shape.

The Dual Tip Muffler for the 1990-97 applications must be combined with a connecting pipe. See the correct Power Pulse Connecting Pipe for either the 1990-95 or 1996-97 (OBD-II cars) application. This exhaust is a “cat-back” emissions legal and meets California sound level requirements.
