ISR Performance - Mazda Miata NA Circuit Spec Exhaust-(1994-1997) (IS-CSEXH-NA)
It was really easy to install, honestly easier than taking the oem one out. if theres a difference in power its very slight in my opinion but noticeable. Finally the sound, its loud, but not loud enough to annoy people and bring unwanted attention. The tone is a lot deeper than oem and catless. It has a deep rumble at idle and between 2-3000 rpm theres a little rasp and then evens out, overall a great exhaust, the tip is also massive but somehow fits, although might scrape over speed bumps or driveways if they’re steep or the car is lowered.
Its loud but not ridiculous. It sounds good.
It also came pretty quick.
Install is a piece of cake too
