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.
UPDATE LATE 2105: 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 just installed the Borla exhaust on the MX5. Sweeeeeeet!
We last spoke in November about some upgrades for my 2011 MX5 soft top. It
has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my
car were well worth the effort.
Installation of the RoadsterSport ceramic coated street header was straight
forward and took under 8 hours, including a 40 minute test drive and cleanup
of the garage! Combined with the RoadsterSport Q exhaust, the sound is
fantastic and the increased torque, horsepower and performance make it a
blast to drive.
The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM
front power train and X braces really enhanced the ride - minimal body roll,
comfortable and very responsive.
Your recommendations really helped transform the car from great to
fantastic. Your research, product development and candid recommendations
make you a standout in the industry.
My only questions are - what's next on my list .... And how soon will my
wife want the same upgrades on her 2012 PRHT ...
Again, thank you!!!
