He obviously didn't know what it was dude, relax. Let's not turn this into NAZIoc.
Anyway... Especially if you have an aftermarket header and/or up pipe, or you plan on keeping the stock pieces forever, take the time to wrap them with some kind of thermal wrap. Personally, I'm not trying to promote anyone in particular, but DEI makes some titantium mesh heat wrap. I put that on my header and up pipe and I have a little more left that I'm going to wrap the hot side of my turbo with, and then put the heat shield back on.
If you do a good job, you'll see better boost response and even boost coming on a few hundred RPMs sooner.
