RoadsterSport Super-Q Muffler for 2016 Mazda MX-5 (ND)

Описание: Following the huge popularity of our NC application "Q" Muffler this Q for ND is once again "Q" for Quiet version. 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 where many exhaust choices drone). Smooth mandrel bent tubing redirects the flow for a side entrance to the muffler where we engineered a three chamber design. It would be much cheaper to just use a single big muffler with nothing but perforated pipe through the center surrounded by sound absorbing materials, but doing it right with the three chamber design allows us to tailor precisely the FUN sound you want when you push it toward redline, without the harsh drone on decel that the more simple designs make you suffer.

This triple 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 triple chamber design features an exclusive 'Helmholtz Resonator' first chamber that massively reduces the standing wave inside the exhaust system, reducing the 'booming' tendency by over 50db inside a top up Miata cabin that is common on many aftermarket Miata exhausts. To create this Helmholtz chamber we outfitted our 2016 ND Gen Miata with a computer and sound analyzer and microphones and drove it under varying conditions and loads and without the stock muffler for the computer to carefully measure the sound spectrum coming out the stock midpipe. We then use that data and some special software to calculate the particulars of the Helmholtz chamber size and valve specs to precisely knock down the frequencies we do not want to hear in the new Miata while allowing the good throaty burble fun sounds to pass through. The result is deep throaty fun, without the drone!

The Helmholtz chamber gives this muffler a dual personality, under decel it is super mild and quiet, yet when you push hard toward redline it gets more fun and racy! With the top down lots of fun throaty burble, but dramatically more tame when the top is up. 22 pounds. In brief, FUN when you want it, and yet totally mild when just cruising top up.

Yes, simple BOLT ON install, just two bolts!
