  1. Anybody running a sbp pipe and cns carb. I have the cns carb on stock exhaust and my bike runs TIGHT! But I want more bottom end! Any body running that setup want to chime in and give their $.02

    A smaller outlet opening end increases backpressure. This effectively decreases the powerband to create more low-end torque. It also decreases exhaust tone and enriches carburetion.

    A larger exhaust outlet end decreases back pressure. This widens the powerband at the top end. It also increases exhaust tone and leans out carburetion.
