Mazda Miata Muffler

The Mazda Miata Muffler provides the legendary roadster with the balance of fun and everyday civility, which means that intelligent exhaust design can render the car more fun and protect occupants. Constructed of corrosion resistant steel, the unit directs hot gases to the tailpipe in a series of perforated tubes and chambers, forcing pressure waves to collide, cutting out noise without suffocating, which is a Mazda innovation that fans soon learn to love. Drivers feel the sharp throttle response, since the labyrinth retains sufficient velocity for scavenging, but it also keeps carbon monoxide out of the cockpit to leave weekend cruises safe. It fits all NA, NB, NC and ND generations of Miata in size and hangers, which means that the original owners will not have to worry when changing their car to the recent lightweight hybrid model to keep fit as precise as it was on the classic 1990 model, and they will not break Mazda tradition. A resonant diaphragm on the narrow trims is coupled with the Muffler to focus the high-frequency range and provide the car with the deep yet pleasant burble which has helped Mazda earn its reliability halo. The component withstands the intense heat cycles and spray on the road, and its longevity contributes to the popularity of the brand as having trouble-free mileage. It even serves to keep the fuel economy the same with different engines, whether it is the early 1.6-liter or the present 2.0-liter, by keeping the back pressure ideal. Installation does not change the location of factory oxygen sensors, which allows the computer to make accurate mixtures to achieve clean emissions. Rolled tips and accurate welds are small details that give this system a visual finish that makes it stand out in a saturated performance market. The Muffler has stayed a quiet foundation of any Miata driving experience with its combination of acoustic science, rough-and-ready construction and wide model compatibility.
