Our "resonated" mid-section option will now come standard with large-body resonators for people who want/need an OEM+ sound from their exhaust.

Introducing our new V3 Downpipe Set for the S4/S5, 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 breathe through larger 2.5" piping and smooth transitions. In addition to increased sound (15-20% louder), expect power gains as high as 15HP to the wheels depending on tuning and hardware.

Although our Version 2 pipes were tried and tested on the B8 platform, we weren't quite satisfied with "good enough"

Version 2 - 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 300 cell cats for emissions reduction.

Version 3 - Improved ground clearance for Resonated options based on client feedback!

Our downpipes feature:

  • Improved sound
  • Increased engine response
  • Power increase of 10-12 HP on an otherwise stock vehicle
  • 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 downpipes already and would like to upgrade to catted/non-catted or resonated rear sections you can find them at a discounted price here.
