HFC Downpipes, 2.75-Inch Stainless Steel

The JH Motorsports HFC Downpipes are a performance exhaust component engineered to enhance the flow and performance of the Audi RS5's 4.2L V8 engine. These downpipes feature a 2.75-inch piping diameter, which is considered optimal for the engine's demands, preventing the restriction caused by smaller stock piping and improving flow by eliminating the turbulence associated with transitions to smaller diameters. Constructed from durable 304 Stainless Steel, these downpipes utilize gasket-matched flanges for a smooth transition from the larger header diameter to the downpipe. The kit includes a JHM Performance Race Header Modification, JHM High Flow Catalytic Converters, exhaust manifold gaskets, nuts, and downpipe gaskets. They are designed for direct-fit installation and are handmade in the USA, incorporating 304 Stainless Steel V-bands for secure connections. This product is explicitly for off-road use ONLY and is not legal for use in highway or street vehicles. By purchasing, the user acknowledges and accepts the intended use for racing competition and agrees to indemnify JH Motorsports for any liability arising from use on public roads. These downpipes are compatible with the JHM 2.75" Valved Performance Catback exhaust system. They are designed to fit the Audi RS5, B8-B8.5 chassis (2011-2015), with the 4.2L V8 32v FSI engine.
