Morning guys

Ive recently had a look inside my old sports cat with a bore scope , was just curious if anyone else has see this inside theirs ? (the cat was assumed blocked)
sorry for the shocking image i know you can only just make out the strange bits inside this was taken just before the bore scopes batterys died

Looks like your engine's been eating Marijuana!

The catalyst itself looks OK.  Fook knows what that green sh1t is, if not weed!

You can diagnose a bad cat with one of those infrared temp guns though.  The outlet temp should be a lot hotter than the inlet temp.  If the temp is the same at both ends of the cat, it's fooked.

It has baffled alot of people mate haha , even miltek were confused as to what it actually is
to be fair i really need to get a better scope cam in there for some bright clear pics / videos
it was holding back nearly 30 bhp before i fitted a new downpipe ( pre stage 2+ at r-tech ) so its gotta be pretty bad .
