I have no problem whatsoever with the discoloration. It is a sign of living, it is honest. I do use a so-called 'anti-bluing' product which in fact enhances the patina.

I've rode maybe fifty miles after having installed the EFI silencer, and I've noticed the silencer is already starting to turn gold in places, and the pipe underneath the foot peg is fairly blue - did I do something wrong? What do I do now?

              The blue part of the pipe under the footpeg must have been blue before the muffler change. The muffler change wouldn't all of a sudden cause it; that's where the hot tube is inside the header pipe. Until you cut that out you don't have a "free flow" exhaust & it will just get bluer. Shine light up there, you'll see it.

               Unless I'm totally wrong & there is no hot tube in the UCEs. In that case ignore all of the above.

               But why else would the pipe under the footpeg be blue?

It was not. The stock bazooka had a bit of gold on it and of course the bit around the O2 sensor was getting colorful, but where I had removed the silencer was completely clean chrome before all of this.

As long as I'm not wrecking the bike or anything, I guess I don't mind too much. She's more spirited this year than she was last year, that's for sure.

My Hitchcocks' front pipe coloured blue and gold in the first day - loving it. (it is however wrapped at the moment)

................. why else would the pipe under the footpeg be blue?

There is an anti-crush reinforcement ring inside the stock header where the muffler bolts on.  Once you place a free flowing muffler on, this then is a choke point - and - it turns blue.
