Bolt-on more horsepower, torque and boost response!

When designing the 2.0T FSI & TSI motors VW thankfully increased the size of the K03 turbocharger. Unfortunately they designed the downpipe like a brick wall. Rule #1 in turbocharger theory is reduce backpressure at the turbo discharge. With the factory downpipe 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.

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 factory cat-back exhaust. Double layer graphite gaskets and grade 5 locking hardware keeps everything tight.

The modular nature of our 3" downpipe allows for changes to be made at any time without cutting or welding. On race day, the catalytic converter can be easily removed and replaced with a test pipe. Is your aftermarket cat-back exhaust too loud? Our offset pipe can be replaced with a resonated pipe at any time. The stock cat-back adaptor can be replaced with a 2.5" or 3" adaptor, or a bolt-on cat-back system. (coming soon of course)

Our 3" downpipe is currently available in 4 configurations. Street series systems include a Magnaflow catalytic converter. Race series systems include a test pipe. Both series are available resonated. All plug&play components can be purchased separately. (listed to your left) All configurations can be purchased ceramic coated.
