Life is about to get interesting

Ceramic coat the exhaust and belive me no matter if it is carpenter/viking/ces/ zard they get hot hot hot hot

Yes any and all get hot. The Carpenter and CES will give you more top end but the Viking will give you great low end pull and a bit more distance between your leg and the exhaust. Very much so a very friendly rider designed system.
 
I like the 3-1 exhaust. But, want a nice sound and not sure what is also cost effective.
Carpenter seems to have the lowest price on a 3-1 exhaust. It has a very low rumble, and allows for the most hp. Combined with the K&N RX4040 filters, and a good tune you will have a lot of power to tame.
 
Ever notice how it's the pipes for fast bikes that have springs? One day you'll get a motor with enough hp to need springs too.
