Its the piece right after the cat on FED models. Has an O2 bung on it.

Bought a cat back exhaust but my car is CALI spec, so I was gonna see if anybody had one and wanted to part wth it before I went and had a muffler shop fab one up.

PM me if you have one and a price shipped to 84084.

Thanks in advance
