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 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). Sorry, we will not ship these to residents of California.

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.

INSTRUCTIONS: Read full installation hints and notes in our forum Installation Instruction Section! --- CLICK HERE TO READ MORE. YES, fits both manual and automatic.

Customer Reviews

RoadsterSport MAX Power MX5 Miata Stainless Steel Header

Beautiful piece of hardware and what an improvement! I've spent years building cars and I've never seen a part as nicely designed and manufactured. Completely changed the character of the car. Sound is amazing and the performance increase is obvious. I get all sorts of awesome sounds out of her now (pops and burbles and all that).
Install was straight forward using the instructions in the forum. I do suggest replacing gaskets at both ends at the same time.

I was concerned these pipes were going to be too loud, but they are just right while running with the SuperQ muffler and HighFlow Midpipe. I find myself driving with the radio off more often than not and I am really just enjoying the car itself.

The car has gone from hairdresser straight to barber status.

I have relocated the O2 sensors to the Midpipe and had the car ECUTEK tunes & there are no CELs.

Excellent product. Easy to install and makes a wonderful sound. It curiously also reduces the underhood temp quite a bit over the stock header and fat cat.

I installed the Roadster Sport Max Power header along with the Roadster Sport Midpipe and Super Q 2 Muffler. The entire system has been flawlessly crafted, it is almost a work of art. The sound is about 20ish% louder and it has a nice throaty quality to it. I really enjoy the burble on decel and the slight backfire when raking through the gears. The power gain is noticable, it comes on strong from 4k or so on up.

The install of this system went well and everything fit together nicely. Be careful when removing the old header as the forward O2 may hang up on the alternator, which mine did. I ended up ripping the plug off the O2 sensor and they are very expensive to replace. As a fix I cut the end off my new extension wire and used water tight butt connectors to connect it directly to my old O2 sensor.

I'm looking forward to ordering the ECU tune in the not to distant future to complete the package.

I recently installed the header in my 2012 MX5 soft top which was very easy by following the recommendations provided on this forum as well as The change in torque is substantial: 2nd and 3rd gear really came to life! I added the mid-pipe also and was fearful that the sound of these two additions would be over the top with my RS II muffler. I should not have worried, I love the sound! Yes, its a little louder but in a good way. No need for the "Q" for me. The header and mid-pipe are of excellent quality as I have come to expect with GW parts. Thanks to Brian and his team for making these products available!

The header fit and finish was per perfect just like expected. Install went just like Brian explain in his instructions only thing I added was extra heat shield on the back of the alternator.

Outstanding quality both the header and the mid pipe and combined with the Q muffler it sounds awesome yet mellows out at freeway speeds.

Purchased the RS Max Power header and midpipe. THESE ARE TRUELY A WORK OF ART! CRAFTMANSHIP IS TOP NOTCH!! SITE PICS DO NOT DUE JUSTICE TO THESE ITEMS! I recommend Brian's site to ANYBODY with a Miata/MX 5. Brian and Co have taken a great automotive platform and elevated it to it's FULL POTENTIAL!

BTW - the RS header and midpipe sound freakin' nasty with my Mazdaspeed rear muffler - not as loud or as ugly as the MX-5 Cup exhaust sounded, but pretty damn mean! I LOVE it! And, the Fidanza FW/Exedy clutch combo are darn near perfect.
