Good-Win Racing makes and sells more MX5 Miata Exhausts than any other company, and we use that experience to help YOU find the best MX5 exhaust choice. We provide an estimate of how much louder each exhaust choice is over stock sound levels in the product description for most of our MX5 Miata exhausts. We have MX5 Miata exhausts designed for street use, race use, as well as MX5 Miata exhausts designed to handle a performance header or supercharger. One VERY important factor to consider is how factory options change the listening environment of the MX5 driver. The driver of a manual transmission soft top equipped MX5 Miata has a VERY different vehicle in terms of sound dynamics than does the owner of an automatic transmission equipped folding hardtop MX5 Miata. Street drivers of otherwise stock manual transmission soft top equipped MX5 Miatas tend to prefer exhausts choices such as our best selling RoadsterSport II or our Racing Beat dual tipped exhaust. However, owners of automatic equipped MX5 Miatas, and any MX5 owner with a folding hardtop, usually prefer the RoadsterSport SuperQ Dual exhaust. All owners considering further modifications such as performance headers, performance midpipes, and superchargers, are strongly encouraged to consider the RoadsterSport SuperQ. Finally, we offer "Race" singles that are designed for the sound limits of SCCA events and tracks such as Mazda Raceway Laguna Seca, though some will find them appropriate for their street use. If you have any questions about which MX5 exhaust is best for you, please contact us today.
Note that EVERY brand of exhaust we offer will unmask the burble and 'pops' of unburned fuel that are NORMAL in every exhaust system but normally below the hearing ability of the average consumer. If you have no idea what I am talking about in the last sentence then please go on YOUTUBE and search "sports car exhaust pops" for a quick education. Funny story about exhaust 'pops' when the good folks at BMW designed the MINI they wanted to make it feel less econobox and more sports car and they included a highflow exhaust from the factory so consumers could hear the fun pops from the first test drive.
UPDATE....A revolution in exhaust technology finally in a Miata application, our new HELMHOLTZ midpipe features an exclusive side branch resonator that massively reduces the standing wave 'boominess' inside the exhaust system BEFORE it gets to your muffler of choice! Cuts the 'booming' frequencies of 120-130hz by 48+db inside a top up Miata cabin which is a common source of complaints with aftermarket exhausts on the MX5. Result is all the FUN throaty sounds you want, and no drone!

I red'all the parts in the order I placed and installed them in my car yesterday.
I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have.
Thank for great products and service.

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
