I am sure yosh makes a all ti trc slip on. You probably can't get it through a distributor. You will need to call yosh directly or go through a dealer of yosh directly. Yosh will make alsmost anything for enough money. I will warn you right now that it will be costly. I don't know what to do because I am not going to buy a new full ti system because they cost too damn much. So I am trying to find a used full ti system for a good price. Preferably a akro, but also looking for arrow, leo vince, and yosh or whoever. I really like the looks of the race fit, but way too much money for a slip on.
So I was thinking of just getting a yosh trc slip on, but really don't like the stainless on the carbon slip on. To custom order a all ti one is too much. I also don't like the looks of the slip on as much as a ti trc full system. The back of the trc does not stick out as much and has a bigger pipe diameter on the full system.
I will just wait and try to find a good deal or piece my own exhaust together from used ones I find. The stock exhaust on the 06 is pretty decent and it is not a big priority. Getting the turbo bike running is top priority and I need all of my money for it.
