V3 Cast Catless Downpipe

The Canadian Auto CAP-EXH-097 represents the V3 iteration of their cast catless downpipe, specifically engineered for the B9/B9.5 Audi S4/S5 3.0T platform, covering model years 2018-2025. Constructed from cast 304 stainless steel, this downpipe offers superior strength, smoother internal flow transitions, and enhanced thermal stability compared to previous versions or standard stock components. It features TIG welded and back-purged construction with precision-cut CNC flanges for an OEM-like fit, ensuring no cutting or welding is required during installation. The V3 version is available with an integrated heat shield, designed to reduce engine bay temperatures, protect nearby components like wiring and fuel lines, and potentially improve air intake temperatures for better engine performance. Owners can expect a more aggressive and deeper exhaust note from their vehicle without the presence of drone when paired with the stock exhaust system. The product includes all necessary hardware, gaskets, and bolts for a bolt-on installation, which is generally estimated to take around two hours, though professional installation is always recommended. Important considerations include that the removal of factory catalytic converters will trigger a check engine light, and software tuning is recommended to maximize performance gains. The product is explicitly stated as being for Racing Competition use only and is not legal for highway or street vehicles. Canadian Auto Performance makes no representations or warranties regarding compliance with applicable emissions standards, and the buyer is responsible for understanding and adhering to local laws and regulations.
