GAS Downpipe Set, 4M Q7 3.0T Supercharged

They're finally here! Introducing our new resonated downpipes for the 4M Q7 equipped with the 3.0T supercharged engine. These are the first aftermarket downpipes available for the 4M platform, solving the dreaded rattling flex pipe issue in the Q7 while improving performance and longevity. 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. Expect power gains as high as 12hp (depending on tuning and hardware) without adding noise or rasp!   Features: Slightly deeper sound Increased engine response Power increase of 8-10hp on an otherwise stock vehicle (more with tuning) Full 2.5" (62.5mm) diameter, terminating at 60mm sleeve clamp fittings to ensure perfect fitment with the OEM exhaust system V-band connections for strength & adjustabil
