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 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 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.

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

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
