42 Draft Designs - Transverse 2.0T FSI / Gen 1 TSI Downpipe

42 Draft Designs

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 also 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.

The modular nature of the 42DD 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? the 42DD offset pipe can be replaced with a resonated pipe at any time. 

The 42DD 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 in resonated and non-resonated configurations. 

Please note that the non-catted (Race) version of this downpipe is for off-road use only and is not to be installed to a street driven vehicle.

  • Fits 2006+ VW Mk5 Golf, Jetta, GTI 2.0T, Mk6 GTI, B6 Passat, CC and Audi A3
  • Fits both FSI and TSI including CCTA and CBFA
  • Included adaptor allows fitment to stock exhaust
  • Will fit any cat-back exhaust with 3" or stock diameter

Please note! 42 Draft hand builds each downpipe, and there may be a 7-14 day delay between when the order is placed and the downpipe is shipped to you depending on their current workload and stock level.
