Ilmberger carbon is made from 'Pre-Preg' carbon sheet so is the expensive very lightweight F1 style stuff. It is finihsed in a clear plastic coating that is very glossy.
Hand laid carbon is made in the same way that you would lay up a glassfibre part by hand, so is slightly heavier than pre-preg. The finish is in clear gel coat which isn't quite as glossy as the Ilmberger type, but still good and doesn't need paint.
Both types use the same weave pattern so you can mix n match on the bike without it looking odd.
Ilmberger don't make a carbon version of the stock dual seat unfortunately (although they do make a passenger seat cowl), so if you wanted a full dual seat option then it would only be the hand laid version that is available from us.
We don't sell exhaust wrap I'm afraid. I have used it in the past but only to protect full race fairings from exhaust heat etc. To be honest you will find it very difficult to get a pleasing result without taking the headers off to wrap them as it is quite fiddly to do in situ. Also you will need the protection spray for the wrap once you have put it on, otherwise they look very tatty in a very short space of time

I have heard some say that the wrap actually increases corrocion of the pipe as they trap water, but haven't noticed this myself when I have used it.
