RoadsterSport "Q" Stainless Steel MX-5 Miata Exhaust 2006-2015 NEW!
We now have THREE exhaust choices for the 2006 and newer MX-5 Miata, including the RoadsterSport RACE, our best selling RoadsterSport II Duals, and now this duals unit we affectionately call the RoadsterSport Q.
This unit is the most mild...about 10% louder than stock on otherwise stock NC...with a deep burble. This unit was designed to handle future mods including the massive sound gain caused by a header change (either our RoadsterSport header or our Racing Beat header). Removing the factory header means removing the first catalytic converter which is also a very large resonator. The result of the header change is a massive amount of additional sound down the exhaust tubes. Developing a muffler that could both deliver all the flow of our other RoadsterSport designs yet swallow the sound unleashed by the header was a challenge. The factory muffler does an okay job with the sound from a header change but at the cost of flow and a giving back of much of the hard fought horsepower gains of the header change. By using smooth mandrel bent 2.5 inch tubing to redirect the flow for a side entrance to the muffler we engineered a sound wave attenuation first chamber to knock down volume level dramatically while maintaining a flow-through design.
Our latest and best dyno results for the header change which are in our forum were obtained with this muffler....all the flow, without all the noise! Yes, simple BOLT ON that bolts to our midpipe, or the factory midpipe, or our Racing Beat midpipes. Weight is 24 pounds.
