Full exhaust system (including muffler & mid-pipe + test pipe) made by Jet’s for the NA Miata (1989-1997). It’ll fit both 1.6L and 1.8L and it’s made for racing since it comes with a test pipe to replace the catalytic converter. It gives a nice bump in power to naturally aspirated engines. DISCONTINUED AND NO LONGER AVAILABLE.
