SUPER-Q Stainless Steel Muffler

The RoadsterSport SUPER-Q Stainless Steel Muffler (60-13372) is a premium exhaust component engineered specifically for the Mazda MX5 Miata NC models from 2006 to 2015. It aims to provide the same desirable sound under acceleration while being more effective at reducing boom and drone during deceleration. Constructed from stainless steel with smooth, mandrel-bent 2.5-inch tubing, the SUPER-Q muffler utilizes an innovative attenuation chamber design. This system effectively knocks down overall volume levels, making it a premium 'no-drone' choice. It is highlighted as an excellent option for both manual and automatic transmissions, with a particular benefit for automatics that tend to operate in lower RPM ranges. The muffler is only slightly heavier (170g) than the standard Q model and comes complete with new nuts, bolts, and a gasket for a ready bolt-on installation. Included with the SUPER-Q are standard, removable baffle cones, allowing users to fine-tune the exhaust note to their preference. The design is described as the most mild and mellow on an otherwise stock MX5, producing about 10-15% more volume than stock, with a deep sporty burble during acceleration and quiet operation during cruising. For those planning further modifications like superchargers or header changes, which can significantly increase sound levels, this premium MX5 muffler is recommended as the best choice to manage the sound without compromising flow.
