It's a tumor........
Pre-cat.
I'm in the process of getting ready to turbocharge my xj and was making sure it wasn't a cat.
It isn't lined, and it can (and is) still a resonator without being lined.
A resonator is simply a (usually empty) cavity that resonates at a frequency chosen to alter the exhaust note an exhaust system produces, whether it's designed to amplify some frequencies that make the exhaust sound better or suppress others that make an exhaust sound fartcanny.
