Mom's Choice Gas Downpipe Set, C7 A6/a7 3.0t Supercharged Deluxe Edition [9P1IO28U]

Introducing our new V3 Downpipe Set for the C7 A6/A7 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 12HP to the wheels depending on tuning and hardware.

Although our Version 1 pipes were tried and tested, 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 300 cell cats for emissions reduction.

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
• Will not cause a check engine light
• 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! Please reference your original invoice number for faster processing when doing so.
