RoadsterSport "Q" Stainless Steel Premium MX5 Miata Exhaust----APPEARANCE PACKAGE Extended Length Version :: 2006-2012

We make THREE exhaust choices for the 2006 and newer MX5 Miata, including the RoadsterSport RACE, our best selling RoadsterSport II Duals, and now this Premium duals unit we affectionately call the RoadsterSport Q. This unit is the most mild...about 10 to 15% louder than stock on an otherwise stock NC...with a deep burble. This unit was designed with the sound absorbing ability 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.

BRIAN's APPLICATION NOTES: Perfect choice for anyone planning future upgrades such as a header change or supercharger. Also a good choice for those looking for a more than stock but still mellow sounding choice in exhaust upgrades. Finished in three inch 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% louder than the stock muffler on an otherwise stock MX5 exhaust system....and only about 20 to 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. Installation of this Miata exhaust is SUPER EASY...just two bolts! You don't even need to jack up the car, this installation can be done in your driveway! This Miata exhaust is guaranteed for as long as you own your Miata. Proudly made in the USA with a LIFETIME WARRANTY. Fits all 2006 and newer with manual transmission MX5 Miata, automatic transmission MX5 Miata, and retractable hardtop MX5 Miata!

BRIAN'S CONCLUSION: This is the choice on my own MX5 for driving around town...and my strong recommendation for anybody wanting an exhaust with a super smooth burble. This is also our top recommendation for owners of the automatic transmission.
