Show original supplier 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.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
