Thank you. You have rated this product.

Gorgeous! Nothing comes close to our famous RoadsterSport MAX Power Header! Look at those smooth curves! Notice you don't see 6 welded sections for each primary like so many lesser headers that are made from cut pieces of standard radius pipe and straights, instead ultra SMOOTH all mandrel bent tube is used here to keep flow as clean as possible. Sexy all T304 polished stainless steel is formed into equal length primaries for max power...with a lifetime 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 gasket....so 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 header....in 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 connections...one 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 2015 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 with 2.0 liter motor. Our normally aspirated customers making the most power, and our supercharger customers making the most power, are all using this header. In the forums folks are proud to show off lesser headers that have 5 to 8 welded sections for each primary because the maker did it the cheap way with welding up standard straights and radius bits but while they are admiring the welds they overlook that each of those weld points means that inside the pipe you have a rough circle of material instead of smooth pipe! In contrast, you don't see welds on everry primary here because we do it right, smooth mandrel custom bend complete one piece primary sections give you the smoothest possible flow.

The first converter is also a pretty good resonator so understand that installation of any header will raise the exhaust sound level a good 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 RoadsterSport Helmholtz midpipe tunes the final sound result for drone free fun.

YES, fits Manual and Auto trans, both LHD and RHD. Those with AUTOMATIC transmission should read our instructions on install first.

REVIEWS

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!!

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
