Good-Win Racing 2012 Street PRHT

Good-Win Racing MX5 Street Car Project

Introducing our Super Street Miata project. This will be my (Brian Goodwin's wife) daily driver so we are keeping the ride quality as top priority.

However, being a racing family performance is always a must! So we have done a few things and have more in store for this beauty.

Many pages of information and discussion on this project and dyno print outs on the Our New 2012 PRHT SS Project forum thread. Follow along on and let us know what you would like to see us do.

Cheers!

REVIEWS

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.

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!
