Introducing our new V2 Downpipe Set for the S4/S5 and Q5/SQ5 equipped with the 3.0T supercharged engine!

Our high flow downpipes are built completely with T304 stainless steel for high strength, corrosion resistance, and longevity. These downpipes remove the small front resonators (sometimes mistaken for secondary cats), allowing your engine to breath through larger 2.5" piping and smooth transitions. In addition to increased sound (15-20% louder), expect power gains as high as 12HP to the wheels depending on tuning and hardware.

Although our Version 1 pipes were tried and tested on the B8 platform, we weren't quite satisfied with "good enough"

Version 2 revision includes improved fitment and ground clearance, new flex joint position for improved access to downpipe nuts, v-band joints for adjustability, and an added option for resonators or high flow GESI 200 cell cats.

Our downpipes feature:

  • Improved sound
  • Increased engine response
  • Power increase of 10-12HP
  • V-band connections for strength, adjustability, and expansion*
  • Full T304 stainless steel construction
  • Hand TIG-welded and back-purged 
  • Stainless bellows for unparalleled durability and fewer flex joint failures
  • Tailored fitment for increased ground clearance on lowered cars
  • No check engine light - guaranteed!
  • Works well with both tuned and factory cars - a great replacement option for your rattling pre-resonators or blown out flex joints

*V-band connections are compatible with our catted or resonated rear section. If you have purchased our V2 downpipes already and would like to upgrade to catted/non-catted or resonated rear sections please send us an email for special pricing!
