Miata NC RoadsterSport Exhaust

 

Stimulous checks hit and you guys BOUGHT EVERYTHING not nailed down!  We make all our RoadsterSport NC exhaust goodies here in the USA and those factories are ALREADY building our parts 7 days a week currently!  We are doing our best to update the page below as items go in and out of stock, notice items bottom of the page 'out of stock' or 'Prepay' have the estimated ETA in the subheadings when we have such an eta from the factory.   If you don't see the eta there, we really don't have it yet.  Please be patient with our team, we don't run the exhaust factories and we are doing our best to hurry up the process but these items are hand welded one by one and it just takes time and when sales volume suddenly spiked over 500% there is only so much the factories can do.

Good-Win Racing is the ONLY vendor actually owning, daily driving, and racing the NC Generation MX5 Miata.  As a result 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. There is a ton of our feedback and setup advice in the product descriptions for most popular items, in addition to the primer below.  Please click below for more important details, including the function of the Helmholtz Midpipe shown in this picture at left.

Do NOT wrap headers. Wrapping headers VOIDS THE WARRANTY on every brand of header made.  The wrap holds moisture and also gathers petroleum emissions from under the hood like any oil leaking (meaning eventually you can have a fire).  Result includes fast degradation of that gorgeous polished stainless surface and the welds.   Wrapping headers is something that came from Drag Racing, but the Pro Drag Racers know it kills the header in exchange for another 1 or 2 hp scavenging benefit and they accept that it also means they get to rebuild the headers at the end of every race season.  Instead of wrapping headers consider our ceramic coated versions, or our header heat blankets (which don't trap moisture). 

International customers should address their fitment and supply questions to our dealer in Europe and our dealer in Australia (see tab below for "International Customers" for links).  We ship to USA and CANADA only, we know fitment on Left Hand Drive cars only.

VOLUME
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.
SOFT TOP VS. PRHT? MANUAL VS. AUTOMATIC?
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, Street Single, or Helmholtz Race Single. 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. 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.
"BURBLES AND POPS"
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 we're 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.
Helmholtz Technology
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!
