Exhaust glowing more after EVO. blankets?

[powerstroke 350700]

First I would like to ask if this is hard on the exhaust system and the turbo? Second I have the exhaust wraped to the muffler flange, from the flange to the muffler gets cherry red now also when I let off the throttle it pops sometimes and fire comes out the exhaust is this normal and I am worried that my hood will melt there so I am thinking of wraping the pipe and possibly the muffler.
What do you guys think.
Thanks

If it is more cherry red it definitely means it is working. As for whether it is hard on the exhaust system the short answer is probably yes.

I was about to wrap my headers this year and I ended up reading a lot of stuff about how the extra heat will sometimes cause manifolds to crack, and other times cause them to rust away.

The manifold on the 1100Ts is supposedly quite even in thickness, so assuming it was wrapped correctly (right amount of overlap) it should be less likely to crack. A blanket should remove the uneven heating issue a bit. As for rusting, I heard this mainly in regards to dirt bikes, and I can't imagine moisture saying around the manifold on these turbos (dirt bike headers aren't usually cherry red). So you are probably good. Then again, a replacement manifold is $700 (although you could have a cracked one welded).

When it comes to the extra heat I don't see people very concerned about shutting it down and having the heat cook the oil in the turbo. People say to idle it for a minute before shutting it down, but I highly doubt a minute of coolant running through a cherry red turbo is going to do jack **** to the issue of oil being cooked after shutdown. VW turbo charged cars have a pump that runs for 5 minutes after shutdown iirc...

Are you using the steel gasket on the exhaust outlet off the turbo? I was using the graffoil type gasket and as soon as I saw flames and cherrys, I would also experience backfiring everytime I let off throttle. Installed steel gasket, and gone. I would check for leaks.
