Thank you. You have rated this product.

Limited Edition Ceramic Coated. Our regular version is polished stainless, which will bronze and blue in response to the heat of use. As a result, got some requests to do bright silver ceramic coating over the polished stainless, which improves long term appearance and performance (about 3% better dyno results with the ceramic coating, see forum 2012 project discussion).

Gorgeous! Nothing comes close to our famous RoadsterSport MAX Power Header! Look at those smooth curves! Sexy all T304 polished stainless steel is formed into equal length primaries that run for max length to the flange for max power...with a lifetime warranty! Beware some other choices on the market that swap with the factory header like this one but use shorter primaries for less power and use cheap manufacturing techniques with lots of welded standard sections which compromises flow and long term reliability (which is why they won't match our warranty!)

We have included a number of 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.

We also put incredible effort into making the exit at the collector as smooth and perfect as we can get it because this collection point is the KEY to good header flow and we had to make sure this was done as perfect as possible. Note we use the factory collector our fit is as factory-like as possible.

Our collector outlet is 2.5 inches. Curiously, the factory outlet is ALSO 2.5 inches and then the factory exhaust chokes down after that point. For best performance customers should match our header with our midpipe and exhaust so they are running 2.5 inches of flow all the way...but our header will bolt in place of the factory header and connect perfectly to the factory midpipe. Note that we have no O2 sensor connection in our part to keep flow as clean as we can get it but also because we could see no purpose in locating them in the header since doing so will throw a code because pulling the factory header includes removal of the first catalytic converter.

TWO choices on what to do with the O2 sensors with our header. Choice ONE is buy our midpipe which is designed to take both O2 sensors...and includes two O2 sensor before the midpipe's converter and one after the midpipe's converter to help avoid a code by simulating the factory installation before. Second choice is to have an O2 bung welded by your local muffler shop before and after the factory second converter in the factory midpipe to replicate the setup we are doing with our midpipe. Both choices require extension of the O2 wires and WE NOW HAVE THE OPTIONAL SHORT and LONG O2 EXTENSION CABLES ON THIS WEBSITE to make the install plug and play!

CARB NOTICE: Installing this header in the 2006 through 2013 MX5 Miata means removing the first catalytic converter which means this header will NEVER be a California street legal header, never be CARB approved (and therefore legal in California for off road use only).

BRIAN'S APPLICATION NOTES: This is THE header for peak power on the NC, proven results over and over for a decade. Our normally aspirated customers making the most power, and our supercharger customers making the most power, are all using this header (our Supercharged 2.0 2007 makes 308 hp at the wheels with THIS header, our 2.5 liter conversion 2006 makes 221 hp at the wheels with this header, see our forum project threads for dyno prints). The first converter is also a pretty good resonator so understand that installation of any non-catted header like this one will raise the exhaust sound level at least 20%. Therefore, we strongly recommend the RoadsterSport Q muffler with any header change because it was designed to handle the sound level of the header, and our new Helmholtz midpipe will tame the character of the sound before it reaches the SuperQ. YES, fits Manual and Auto trans, both LHD and RHD.

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!!

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.
