PREMIUM ADJUSTABLE Sound MX5 ExhaustPromised for years and we finally got it done, a revised version of the famous RoadsterSport Q that is even more successful at controlling sound for customers making modifications such as high-flow headers and superchargers. It was mostly customers with superchargers requesting an upgraded version of the Q, but we also got some requests for this special version of the Q from some customers running our RoadsterSport Max Power header and some running our PPE Long Tube header. Sounds the same under acceleration...but even more successful at controlling boom/drone on deceleration. Dimensions are the same as regular Q, and just 170g heavier than standard Q. They come complete, ready to bolt on and include new nuts/bolts and a gasket. They also include the standard, removable baffle cones allowing you to adjust the note to suit.
All the other features are the same as the standard Q, see information below copied from product description for the standard Q.
This attenuation design is a premium "NO-DRONE" choice, great for those with manual transmission and especially for those with the AUTOMATIC transmission (which tends to keep the RPMS in the lower ranges). 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. This attenuation chamber design muffler is the most mild and mellow on an otherwise stock MX5 ...about 10 to 15% louder than stock...with a deep sporty burble anytime you hit the go pedal but quiet when you are just cruising.
This premium MX5 muffler is also the BEST choice for those who plan such additional mods as a supercharger or header change (a header change unleashes a massive amount of additional sound). Our latest and best dyno results for an otherwise stock MX5....and for modified MX5's with the header change all the way to supercharged were obtained with the RoadsterSport Q muffler. ALL THE FLOW, without the noise!
