Description

Constructed from premium 304 stainless steel for durability and optimal fitment, these downpipes incorporate 200-cell high-flow sport catalytic converters. This design enhances exhaust flow, leading to faster turbocharger spool-up, improved throttle response, and a more aggressive exhaust note. Installation is straightforward, being a direct replacement for factory parts. However, it is important to note that Stage 2 software tuning is required for proper operation. These downpipes are intended for race use only and are not legal for use on public roads. A California Proposition 65 warning regarding cancer and reproductive harm also applies. These downpipes are compatible with a range of high-performance SUVs including the Audi RSQ8 (2021+), SQ7 (2020+), and SQ8 (2020+), as well as various Porsche Cayenne models (2019-2023) with 4.0T V8 engines.
