Having decided that i want a full system i checked the Hamaguchi AG-hammer. It is a Titanium full system, Titanium front to back. I figured it to be pricey, about the same as the new Arrow. WRONG. Hows $2,500 bucks suit ya. I remember reading the new Arrow is'nt all Titanium, the headers to the collector are stainless and the can is Ti. Was'nt expecting that.
