Twinkeel,
The pipes are just shorties you can find on amazon, DCC, etc. I fitted them to the stock header, welded the joint, slapped some high temp paint on them, wrapped them, and called it a day. If you do wrap them, I think two or three pieces of stainless wire to secure the wrap is just as classy as those stainless clamps.
The tires are are 4" Dunlop K70's, a gorgeous tire IMHO. Keep in mind, you will be unable to fit your stock fender brace with that size tire up front. I have yet to find a solution.
Regards,
Seth
