42 Draft Designs 3” 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.

Fabricated here in the USA, our exclusive downpipe for the 1.8T engine installs without permanent modification. Precise pipe routing and a stainless steel flex section assure hassle-free fitment.

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

To configure this downpipe to meet your specific needs please browse the options above. More information about our exhaust systems is available by following the links below.
