REVIEWS

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G

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.
