Looks can be deceptive, but the key is always identifying and replacing the most restrictive component involved in the flow.

From the opening of the intake to the tip of the exhaust, the entire intake, engine, and exhaust are a vacuum driven air pump and the maximum amount of air that pump can move is set by the most restrictive component… if you find and replace that component, you get an increased flow.

If, however, you replace a component – even if you increase that component’s capability – but it’s not the most restrictive component, the pump’s capacity remains unchanged.

If an exhaust change does increase the overall flow, the “All CatB” maps are designed to correctly compensate for the increase.

Cheers
