Bolt-On Horsepower and Torque
42 Draft Designs downpipe is the single most effective bolt-on upgrade for the Mk4 Volkswagen 1.8T. No other basic physical modification can compete with the power gains delivered by this fundamental upgrade. Simply by reducing backpressure we’re able to create usable horsepower and torque throughout the power band while also improving turbo spool and throttle response.

Street Series downpipes are equipped with a 200/cell high-flow catalytic converter. Race Series downpipes are straight-through for track day. Included adapter reduces pipe size to utilize the OEM band clamp. Additional cat-back adapter sizes are available.
