First, let's start with ....15hp gain! OpenFlash has tested many aftermarket headers during the development of their OpenFlash off-the-shelf (OTS) maps. So naturally they have taken everything that we learned and applied it to the design of our own tuned MX5 NC header. Unlike other headers that sacrifice low end torque for top end power (or visa versa), the OpenFlash Header wonderfully combines both strengths in one beautifully constructed package.
Fits 2006-and-up (NC) Mazda MX5.
The construction of this header is really beautiful, solidly built with perfect welds.
I've initially added the header to a stock midpipe and muffler with very satisfying results. At idle it sounds normal but get on it and your motor roars! Driving in traffic will not get you pulled over for "noise pollution". I've driven with police riding close by and they haven't given me a second look.
