This is a USED two piece performance cat-back exhaust for a Mazda Miata. I removed it from my 1993 model (recently acquired from Josh). It bolts right on - no modification necessary. It provides a bit of extra horsepower at high revs. It's also LOUD. Fine for what's primarily a race car, which is what Josh was using the car for, but since 99% of my driving is on the street, I switched to a quiet stock equivalent exhaust.
This exhaust came in two versions - one for 1996-2005 models, with an O2 sensor bung behind the cat, and another for 1990-1995 models with no secondary O2 sensor. This is the 1996-2005 version. However, Josh took a dead O2 sensor and screwed it in, plugging the hole and enabling it to be used with the earlier cars. So you can leave the exhaust as-is for early models, or replace the dummy sensor with a functional one for later models.
It's a stainless steel exhaust. Between that, plus the fact that it has never seen the road in winter, there is no rust. It is a bit dirty. There is also a dent in the resonator, but it is not punctured. Asking $100, which is about what I paid for a new stock equivalent exhaust (and a GRM discount from what I posted it for on Craigslist). I'm just looking to break even on the deal.
