downpipe heat shields... yay or nay?

this is also posted in the C5 A6 forum.

so about 2-3 weeks ago i did piggie pipes and figured, ehhh why not leave the heat shields in since i didnt destroy them when taking out the pipes. so i put them back in and though everything was ok but now im getting an annoying rattling from the shields when i step on it... aghhh. so either i didnt tighten the bolts enough and one fell out or something else that i can think of. my question is was i stupid to put them back on in the first place (i.e. i should rip/cut them off now) or was i smart (i.e. figure out whats rattling and fix it). i know that most people say they are not necesary when he pre-cats are gone because there is no more restriction thus lower temps. is this true? TIA

Probably not 100% necessary, but I feel more comfortable having them in place. A lot of wiring sits above the turbos and downpipes.

while having my turbos replaced it was discovered that my drivers side heat shield was missing. i had a wire melt that leads to a sensor which takes readings off the flywheel i believe. im on k03s with stock downpipes however. once that changes, i will leave them. i see no harm in them being there.

It makes changing the drivers side primary o2 sensor easier :-)
