The 42DD 3" downpipe upgrade has been designed to squeeze all available power from a street or track driven TT.
Power increases can be felt instantly after installation. Midrange and top end power increases dramatically while
almost no low end power loss is felt. Boost builds steadily without a major spike in pressure. On the smaller K03
turbo cars power increases are maximized by additional modifcations (intake, cat-back exhaust, N75 valve, etc).
Since the 1.8T's initial VW release in 2000, it has been proven time and time again that 3" downpipe upgrades
provide healthy power increases on all 1.8T motors.

The downpipe bolts up with a CNC machined turbo flange. A slight expansion to the stock turbo outlet allows
exhaust gases a smooth transition to 3" piping. A stainless steel flex section accurately placed allows for engine
movement. 42DD's adjustable 3-bolt flange finishes up the first section of our downpipe, allowing for precise
adjustments in fitment and a Magnaflow cat bolts-up and piping makes an S-bend to meet the stock exhaust location.

An adaptor is used to allow bolt-on fitment to any stock or aftermarket cat-back. The whole system bolts together
with grade 5 hardware and triple layer gaskets. Mechanical locking nuts are used to ensure the downpipe never
comes loose.

The 42DD downpipe upgrade is available in two configurations - street or race.

  • Street series downpipes include a high-flow cat, a Magnaflow 200 cell metal cat in a spun stainless steel body.
  • Race series downpipes include a test pipe. Test pipes and cat sections are available separately for those who
    wish to change at a later date. Thanks to the modular flange design the cat can be easily removed on race day
    and reinstalled for street use.

  • • CNC mandrel bent 14 gauge aluminized steel tubing
