Will I need to install a new fuel processor on my Suzuki M50 when I change to larger exhaust pipes?

from one and a half inches to two and a half inchesWill I need to install a new fuel processor on my Suzuki M50 when I change to larger exhaust pipes?It all depends on the amount of flow, or more specifically, the lack of back pressure in the new pipes. Generally speaking, if you change anything involving air and the motor, ie exhaust pipes, intake, filter, etc, you need to adjust the computer or re jet the carbs. It is highly recommended that you alter the intake to make it more free flow and to adjust the computer.
