Our Best Seller!

Promised 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 highflow headers and superchargers. This is also our top recommendation for customers with automatic transmissions, and or customers with the PRHT hardtop, or any customer wanting something deep and throaty when they put their foot in it but not shouting at them when they are just in cruise mode.

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 Miata...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 Miata....and for modified Miatas with the header change all the way to supercharged were obtained with the RoadsterSport Q muffler. ALL THE FLOW, without the noise!

Yes, simple BOLT ON that bolts to our midpipe, or the factory midpipe, or our Racing Beat midpipes. INCLUDES New Gasket and fresh Nuts and Bolts to make your install super easy. Weight is 24.5 pounds with baffles removed, 26.5 pounds with baffles installed (stock muffler is over 27 pounds).

Finished in tips which INCLUDE our exclusive baffle cone inserts which are REMOVEABLE and allow you to set the sound to sporty...or quiet. Also available are optional packed baffles (see separate product description) with which you can quiet it down even more for those using a header or supercharger, or race midpipe, etc. This system is 10% to 15% louder than the stock Miata muffler on an otherwise stock MX5 Miata exhaust system....and only 25% over stock sound level when used with our complete 2.5 inch RoadsterSport header and 2.5 inch RoadsterSport midpipe. Baffles are retained by small hex bolts inserted from well under each tip.

Proudly made in the USA with a LIFETIME WARRANTY, emissions legal in all 50 states! Fits all 2006 and newer Miatas with manual or automatic transmission, soft top or retractable hardtop.
