Cast V3 Catless Downpipe

Introducing the V3 Cast Catless Downpipe from Canadian Auto Performance, a refined evolution for the B9/B9.5 Audi S4/S5 3.0T. This downpipe is constructed from cast 304 stainless steel, offering enhanced durability and smoother flow transitions compared to previous versions. An integrated heat shield is available to help reduce engine bay temperatures and protect nearby components. Key features include TIG welded and back-purged construction for strength, precision-cut CNC flanges for OEM-like fitment, and a bolt-on installation process that includes all necessary hardware and gaskets. The design focuses on enhanced exhaust flow, aiming to increase horsepower, torque, and turbocharger response while producing a deep, aggressive exhaust note without drone when paired with the stock exhaust. Important considerations for installation and operation include the fact that removal of factory catalytic converters will trigger a check engine light, and software tunes are recommended to maximize power gains. Professional installation is recommended, though the estimated install time is around 2 hours. This product is intended for Racing Competition only and is not legal for use on highway or street vehicles. The product offers a lifetime warranty and guaranteed fitment for the specified 2018-2025 Audi S4/S5 3.0T models. Owners can also opt for a heat-shielded version to further manage under-hood temperatures and protect sensitive engine bay components.
