Designed as a bolt-on replacement for the factory midpipe to carry the 2.5 inch outlet of the factory header, and our RoadsterSport and Racing Beat headers, all the way to your choice of any of our 2.5 inch inlet RoadsterSport mufflers. Simple Bolt on for MANUAL TRANSMISSION ONLY, can be installed on Automatic but see page four of our forum header install thread for details of what is required. Also bolts up to our Racing Beat exhaust, MazdaSpeed exhaust, stock header and Racing Beat header.

INCLUDES TWO O2 SENSOR CONNECTIONS which gives YOU the option to later add our RoadsterSport or Racing Beat headers and avoid engine codes (by using our O2 plug and play extension cords to relocate the factory O2 sensors to before and after the converter in this midpipe).

All stainless steel construction for years of driving pleasure. This MX5 Miata midpipe is slightly larger diameter than stock at 2.5 inches all the way through (see torque gains in our forum dyno thread). Uses high quality SPUN catalytic 5" converter with metal core (despite presence of converter this unit is not CARB approved...which makes it legal in California only for off-road/race track use). Uses monster 18 inch resonator because when you uncork this NC MX5 Miata motor it wants to get loud unless you use a resonator this large (by comparison stock resonator is about a foot long).

Stock midpipe is 20 pounds, our midpipe is 16.5 pounds for total savings of 3.5 pounds. Despite very large resonator, this midpipe will raise the final sound level just slightly because of the higher flow larger diameter tubing.
