Product Description

Good-Win Racing RoadsterSport headers are made with all-T304 polished stainless steel and come with a lifetime warranty.

We have included a number of features into our MX-5 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”. Curiously, the factory outlet is ALSO 2.5” 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” of flow all the way, but our header will bolt in place of the factory header and connect perfectly to the factory mid-pipe.

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.

There are three choices on what to do with the O2 sensors with our header.

Choices #2 and #3 require extension of the O2 wires using the Racing Beat wiring kit.

1) simply open-air mount them in the engine bay (or unplug and remove them) and they will throw the same codes in the same manner as if they were in the header.

2) 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.

3) have O2 sensor bungs 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.
