Show original supplier description
The Integrated Engineering downpipes are a performance exhaust upgrade crafted from durable 304 stainless steel tubing with a 2.5-inch (65mm) diameter. Designed to replace factory resonators, these downpipes free up the exhaust flow, resulting in a deep, throaty engine sound and noteworthy horsepower gains of 8-12 HP. They feature fully lined flex sections that are guaranteed not to collapse and are approved for use with supercharged applications. All necessary hardware and clamps are included for a hassle-free experience. Integrated Engineering, LLC disclaims any and all representations, warranties, or claims regarding compliance with applicable emissions laws. Fitment includes the Audi S4 (2009-2015 B8/B8.5), S5 (2013-2015+ B8.5), S5 Cabriolet (2009-2015 B8/B8.5), SQ5 (2008-2017 8R), Q5 (2008-2017 8R), and A6 (2010-2018 C7), all with the 3.0T Supercharged engine. A crucial note for fitment is that these downpipes do not fit B8 S4/S5 chassis equipped with 4.2L V8 engines.
