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! **Designed for race use only, not legal for street and/or highway driving in California.** 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 street customers looking for complete system that has a mild purr while cruising to work during the week and throaty rumble when pushing hard on your favorite off-ramp or canyon road.

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 Standard Midpipe. 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).

The header and midpipe are legal for offroad race use only in California, and not CARB approved. Sorry, we will not ship these to residents of California.

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

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
