Re: Boredz V49 - Canucks optional :P
I know Ill have to remap. The Yosh header I had was basically identical to OEM, sans SET valve, and lighter.
this one collects different (4 to 1 vs 4 to 2 to 1) and is MUCH larger diameter from the collector back. That and that it is a standard system when my bike has always been tuned for a shorty it will need a tune.
sounds a lot deeper, and way different at idle probably due to the collecting order.
