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
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.
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.
