Exhaust / header wrap, good or bad Options

[Joe Ricard]

So while I was laying there under my car (I just do that) while swapping out the transaxle I noticed something.
I looked down the SSI pipes and saw nice clean (like perfect burning plug color) from the exhaust port all the way to the line where the heat shroud stops. After that the pipe is black or very dark brownish black out to the flange.

So would wrapping the rest of the pipe in header wrap maintain the heat and extend the better burn all the way through the pipe? Also will wrap the Bursch collector pipes.

Bottom line will it make more power!
