DESCRIPTION
The ISR Circuit Spec Exhaust features 2.5 inch brushed stainless steel piping and flanges, and a polished stainless steel muffler with large 4 inch tip. Fits 1990-1993 1.6L Miata.
This is the most aggressive exhaust option we offer. Simple straight-through muffler with minimal sound reduction and no drone control. For those looking for and happy with a loud car.
For more 'civilized' exhaust options, look to our RoadsterSport and Racing Beat offerings.
Includes:
1x Midpipe
1x Stainless steel muffler with 4" tip
4x 2.5" Exhaust gaskets
6x bolts
6x Nuts
Brian's Thoughts. If you want it really loud and raw and untamed, this is the way!
Far too raspy, and with too much drone, in my experience for any street Miata for anyone much over about 21 years of age.
