ISR Performance Circuit Spec Cat Back Exhaust Mazda Miata NA 1994-1997 (IS-CSEXH-NA-02)

The Mazda Miata performance exhaust package features a sleek 2-piece design. 

The midsection and tail section are standard and with no variations on those parts. The exhaust features 2.5'' brushed stainless steel piping and flanges, and a polished stainless steel muffler with a 4'' tip.

The current NA Miata exhausts have been tested on the OBD1 & OBD2 1.8L NA Miatas and feature a secondary O2 bung. This will only work with 1.8L NA Miatas 94-97.

Many factory exhaust parts are designed to keep noise levels and vibrations low, but this often results in diminished engine performance. Upgraded exhaust systems are often combined with modified intake systems to improve overall airflow through the engine. The more exhaust you have coming out, the more power your engine can produce.

NOTE:  Will not work on Euro models
