GAS Downpipe Set, B8/B8.5 S4/S5/Q5/SQ5 3.0T Supercharged

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 ce
