2003 A4, 1.8L FWD. Did lots of engine/body/mechanical/other work at the family garage growing up. Know enough to outsource exhaust and truck suspension work cuz it ain't the kind of thing you can do easily at home (no lift, no torches). It looks VERY tight in there, especially the cat outlet to the flex pipe flange bolts. Should I just let the local wrench have at it? The book says 2.4 hours. I believe it.

not too bad at all, get thos bolts from underneath & take the cat up from top, remove airbox

initialA4

3 bolts up, 3 bolts down

they are at odd angles, and can pose a challenge to remove with regular hand tools, especially if they are corroded...
