Lets just agree to disagree on this one. I am 99.999% certain the shield (and the mineral wool insulation under it) is there to stop the exhaust from cooling so the secondary Catalytic Converter can reach "light off" temperature. Bare uninsulated pipe will cause cooling and delay the secondary converter from kicking in.

Well my friend I see this is old so I'm sure you have been educated by now but I just have to ask: how did it feel to be 99.999% sure about something, with all the confidence you could muster proclaim to know something you actually just assumed. That's what happens when you assume. You were 99.999% sure you were correct and ended up 100% wrong smh lmao
