42 Draft Designs Introduces the Audi A3 3" Turbo-Back!
We're both excited and proud to announce the release of our 3" Turbo-Back for Audi A3!
Bolt-On Power and Torque
When designing the 2.0T FSI & TSI motors Audi thankfully increased the size of the K03 turbocharger. Unfortunately they designed the exhaust like a brick wall. Rule #1 in turbocharger theory is reduce backpressure at the turbo discharge. With the factory exhaust installed, exhaust gases exit the turbo and wastegate only to meet a dense catalytic converter. By increasing the size of the piping to 3" and moving the catalytic converter further away from the turbo, exhaust gases can mix naturally and develop momentum before being filtered through the catalytic converter. The result is useable power and torque throughout the powerband, quicker throttle and boost response.
Attention to Detail
Starting at the turbo, a CNC machined flange allows gases to merge naturally into a tight radius bend. The second bend transitions the downpipe neatly through the exhaust tunnel, separated by a stainless steel flex section. Underneath the car, a custom tabbed flange and CNC machined hanger assembly allow the downpipe to be supported by the factory hangers. Bolting to this flange, a Magnaflow 200 cell metal catalytic converter takes care of harmful emissions without creating a restriction. Along the way, precisely placed oxygen sensor bungs allow for factory fitment of the oxygen sensors on both FSI and TSI motors. Exiting the catalytic converter, a long offset pipe meets an adaptor allowing precise fitment to the cat-back exhaust. Double layer graphite gaskets and grade 5 locking hardware keeps everything tight.
