Thank you. You have rated this product.

Miata Muffler with Dual tips by Borla. The Borla name is synonymous with performance exhaust. This Miata muffler commands attention under acceleration and mellows out under normal driving. Installation of this Miata muffler is easy...but not a bolt on. 50-state emissions legal with a 1-million mile warranty.

On this Miata muffler system you are getting both the final muffler section and a PARTIAL replacement of the stock midpipe BUT you will need to CUT the stock midpipe after the converter to install this choice. For easier bolt-on Miata muffler choices see our RoadsterSport and Racing Beat Miata mufflers.

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.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
