See Extensive additional information in the product listings for each of these items elsewhere on our MX5 exhaust page, including dyno and video links, just short summaries below.

RoadsterSport Max Torque Header! The most torque you can buy in a standard length MX5 Miata header! See Our forum ND thread for many more details on development history, pictures of prototypes, and dyno work. A great choice for customers looking for complete system that has a mild purr while cruising to work during the week and throaty rumble when pushing hard. **Designed for race use only, not legal for street and/or highway driving in California.** Sorry, we will not ship these to residents of California.

MX5 Miata Header features:
-Same 4-2-1 configuration as the factory header but with much longer and much bigger diameter primaries for more horsepower and maximum TORQUE curve in a standard length header.

We have included a number of extra features into our MX5 Miata Header which we believe customers will appreciate. We CNC machine the main flange to match the factory unit, including the bolt hole flange area thicknesses so that we are precisely replicating the factory fit to the head in terms of thread depth and space, etc.

RoadsterSport Stainless Steel MAXMidpipe. All stainless steel construction for years of driving pleasure. This MX5 Miata midpipe is larger diameter than stock at 2.5 inches all the way through for max performance. Uses high quality SPUN catalytic converter with metal core (despite presence of converter this unit is not CARB approved).andnbsp; UPDATED for 2018 this COMBO Now includes new MAXMidpipe with bigger 5 inch diameter 200 CPI converter, nobody offers more flow, be ready for max power normally aspirated, Turbo, or Supercharger.; This new MaxMidpipe is what we use with both our Edelbrock Supercharger and AVO Turbo.; Resonator is non-fiberglass, higher density packing is both more effective than fiberglass used in every other midpipe on the market and unlike all those other choices this resonator will not pack out or burn out over time.

The header and midpipe are legal for offroad race use only in California, and not CARB approved at this time.

RoadsterSport "Super-Q" Header Version Stainless Steel Premium Adjustable Sound MX5 Miata Muffler. 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 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. In brief, FUN when you want it, and yet totally mild when just cruising top up.

Includes our famous RoadsterSport Super Light 3.5 rolled tip.

REVIEWS

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

Brian, Thank you!!! 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!!! Charles G
