DESCRIPTION

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 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.

OXYGEN SENSORS:

Several options on what to do with the O2 sensors with our header. Read below for options A, B and C. Optional oxygen sensor wire extension cables are available as an add-on option with this header. Adding ONE wire extension gets you one long wire extension to move the secondary oxygen sensor to the midpipe as described in option B below. Adding TWO wire extensions gets you one long and one short wire extension for moving both primary and secondary oxygen sensors down to the midpipe as described in option A below.

A) Buy our midpipe and our two wiring extensions available here for simple plug and play install. Our midpipes are designed to take both O2 sensors, and includes two O2 sensor connections for that - one before the midpipe's converter and one after the midpipe's converter to help avoid a code. Buy BOTH of our extensions for that option.

B) Second choice and most common choice is first sensor in the header and second sensor in our midpipe after the converter, which will also avoid a code. For install in the midpipe of both sensors you need both O2 extension cords, but if you put the first sensor in the header you only need an extension for the second sensor. The first sensor will reach header connection but you may have to follow the wires back to the harness and use a razor blade to clear some sheath which has them gathered shorter than they actually are.

C) Third choice is to put BOTH sensors in the header, which will cause a code unless your tuner turns off the code caused by having the second sensor in the header. You don't need any wiring extensions for that option (sensors will reach header connection but you may have to follow their wires back to the harness and use a razor blade to clear some sheath which has them gathered shorter than they actually are).

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

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.

RoadsterSport MAX Power NC Header Stainless Steel - Ceramic Coated

Had this ceramic coated header, catted midpipe and Super Q installed by Joe at Dynotronics, along with an EcuTek tune. Still need to datalog and get a tune revision, but the car runs and sounds great. Quality products!

This header is a piece of art, noticeable power increase. Sound increase for sure but nice with the Super Q muffler.

Maxpower header and Mid-pipe gave my 2010 mx5 the sound of a sports car. Since install I have had multiple people comment on how badass my mx5 sounds!!!

My girlfriend and I were going to an event here in Louisville, KY and we were waiting to get into the fairgrounds and this guy in the vehicle next to us rolled his window down and asked about the exhaust and how it made him want another Miata!!!!

I'm very pleased with the GWR MaxPower header. The build quality is top-notch and installation was straighforward. Coupled with the GWR Roadstersport midpipe and Race muffler the header has definitely raised overall sound levels, especially on acceleration. But after about 1,000 miles of driving the overall exhaust sound at highway speeds has mellowed sound.

Even though I'm still waiting for an updated tune I can already tell the header is allowing the car to make more power, especially low-end power. I'm finding I have plenty of power in second gear on the autocross course, and on the street I'm finding I have enough power around town that I don't need to downshift from third to second for power coming out of turns as I did before.

In short, GWR has produced another superb product!

I Combined this with the rest of the GWR setup, Mid Pipe, Exhaust and now I got the header, here is a few things to take notice, i drove a good while with just the GWR Exhaust and Mid-Pipe and the extra performance is noticeable but minimal , it was more for the sound than anything and without a Tune you won't feel the extra ponies, as for the sound with just the Mid and exhaust it was great, nothing loud at all and after a while you wish you had more noise, now as soon as i installed the header, there was no doubt noticeable gains and differences, First the sound did increase and in a very good way, sounds like an angry bee, just the way i liked it, turns heads all the time. as for the performance , at first it isn't responsive fast enough and the more you drive the more you will see the difference,after a while it was nothing but fun! and i am taking about a 6AT, more mid and high end power, So after all this, you have to do a Tune! which i did the next day, i sent in the ECU for Bench tuning! the pitch and noise changed afterwards to a perfect sound but the fun is priceless, as Brian mentioned before, start with the Headers plus Tune if you want to see performance and this is my choice!

Oh one more thing, make sure you get both 02 sensor extension cables,

Great product!!!! I installed the header, RoadsterSport Race muffler, and mid pipe with converter. The header is well finished and fits perfectly. Installation just takes some patience.

Installed a full Goodwin exhaust on my 2009 MX-5 in Dec. 2013. Just wanted to put my 2 cents in that these components are works of art! Very nicely done and for a split second I had to debate if I was going to install it on my car or just hang it on the wall. (I went to High School in the 70's so the stuff we could get back then seems downright stone age in comparison).
