Exhaust Systems and Components


Racing Beat Power Pulse System '90-'97

The Power Pulse Miata Exhaust System uses a 2.375" OD stainless steel straight flowing midpipe connected to a 304-stainless steel muffler with 3.5" OD exhaust tip all polished to a show car shine.

The internal design of the muffler incorporates steel and ceramic baffling to create a lower, meatier exhaust tone. This is paired with a presilencer in the midpipe that all works together to give you a little more power, a more pleasing exhaust tone, and no harsh or buzzy frequencies.

Fitment and Emissions: Kit comes with all necessary mounting hardware. This system bolts to the factory catalytic converter, and should be compatible with any other catalytic converters or straight pipes that use the same factory attachment methods.
Since this system retains the factory catalytic converter, it should be emissions compliant. As with all modifications, it is up to the buyer to verify the legality of its use on public roads.

Important. Purchase of the dual tip muffler will require cutting of the rear bumper skin to provide an opening for the new exhaust tip. The kit comes with a template for proper sizing and placement of the hole.

Please call for any help needed in choosing the correct parts for you car. These components are made in batches, meaning delivery dates and shipping times are estimates.

Racing Beat Power Pulse Muffler '99-'05

The Power Pulse Miata Exhaust System uses a 2.375" OD straight flowing midpipe connected to a 304-stainless steel muffler with 3.5" OD exhaust tip all polished to a show car shine.

The internal design of both the single tip and dual tip muffler incorporates steel and ceramic baffling. The dual tip also contains an internal 'Y" shape to ensure equal exhaust flow out of each tip. Both mufflers are bolt on replacements of the stock muffler that give a more pleasing, deeper exhaust tone and a little more power, with no harsh buzzy frequencies.

Fitment and Emissions: Please specify the year model and whether your car is an automatic or manual transmission. Kit comes with all necessary mounting hardware. This system bolts to the factory midpipe and use the factory exhaust hangers.

Since this system retains the factory catalytic converter, it should be emissions compliant. As with all modifications, it is up to the buyer to verify the legality of its use on public roads.

Important. This is for the muffler only, and does not include a midpipe. This generation Miata uses a catalytic converter that is welded into the stock midpipe instead of bolting in separately, meaning Racing Beat offers no midpipe option for NB Miatas.

Important. Purchase of the dual tip muffler will require cutting of the rear bumper skin to provide a wider opening for the second exhaust tip. The kit comes with a template for proper sizing and trimming of the existing hole.

Enthuza Dual Racer System '90-'97

Racing Beat Power Pulse Dual Tip Muffler '99 -05

Enthuza's Dual Racer cat back system is offered in 2.25", 2.5", or 3.0" diameter, all mandrel bent 304 stainless tubing with twin Magnaflow mufflers and 3" beveled exhaust tips. The midpipe includes a resonator for non-turbo charged applications.

Turbo charged cars may see better spool behavior and better ability to control boost creep with the 3.0" system depending on their waste gate design and specific turbo.

Fitment and Emissions: Kit comes with all necessary mounting hardware. This system uses the factory style exhaust flanges, and should be compatible with any other catalytic converters or straight pipes that use the same factory attachment methods and have a matching diameter.
Since this system retains the factory catalytic converter, it should be emissions compliant. As with all modifications, it is up to the buyer to verify the legality of its use on public roads.

Enthuza Racer System '90-'97

Enthuza's Racer system offers a stepped, increasing diameter design which reduces restrictions on exhaust flow and focuses on an increase in performance. Sound control is handled by a Borla muffler, and an optional resonator in the midpipe. This exhaust offers a pleasing, classic sports car sound, but will be louder than stock.

This same system is also offered in aluminum at a cheaper price, for those owners needing something easier on the wallet.

The Power Pulse Dual Outlet muffler is produced entirely from 304-stainless steel for superior durability and appearance. The muffler design incorporate steel and ceramic baffling, to provide the Miata with a deep, throaty exhaust note - without any harsh, buzzy or "raspy" sounds.

The muffler tips are 3.5" in diameter, and the polished stainless. This provides years of good looks you can be proud of. The muffler uses the stock exhaust hangers and exhaust flange designs, meaning it bolts in with no modifications needed. All installation hardware is included.
