42 Draft Designs 3” downpipe is the single most effective bolt-on upgrade for the Audi A3 Quattro. 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 useable 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 FSI/TSI 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 adaptor reduces pipe size to utilize the OEM band clamp.
