This is the exhaust we designed for our V8 conversions. It's a true dual exhaust setup that uses a custom-made muffler that is effectively a pair of mufflers with an internal crossover pipe. A set of headers specifically built for V8 Miatas is also part of the system, and it includes two high-flow metallic core catalytic converters that will keep OBD-II systems and emissions testers happy without a cost in output. This is a complete system from exhaust ports to tailpipes.

As with all of our exhaust systems, this is bent out of stainless steel using a CNC bender for minimal welds and maximum accuracy. The entire system is made of stainless steel and carries a lifetime warranty. The cats have a 5 year/50,000 mile warranty on the shell and a 25,000 mile warranty on their emissions ability.  Please note that we cannot ship this product to California as the cats are not CARB approved.

Available for all NA, NB and NC Miatas using our mounting kits. The NC version is built to clear the Camaro AAM differential, while the NA and NB are built to clear the CTS-V Getrag diff. Will probably not fit other applications. The headers are also available separately if you don't need the complete system.

You can hear it running at the beginning of this video. We are working on better videos for sound.

Perfect Ballance
Great V8 sound with no drone. Quiet enough to not be intrusive on conversations while cruising and just the right amount of authority when the throttle is opened. No signs of restricting performance as a very healthy dyno chart confirmed (LS376/480).
