This pair of big bore silicone hoses connects the Y-pipe to the turbo inlet pipes on the 2.7T in the B5 Audi S4 and RS4 and the C5 A6 and Allroad. 034Motorsport points out that the factory Y-pipe and inlets are only about 2" across for more than two feet, which restricts flow as builds go past typical Stage 3 power levels, so these hoses run a full 2.5" through to the lower RS4-style inlet pipe. The hose inlets are sized for the RS4 Y-pipe, suiting 034Motorsport's high-flow carbon Y-pipe, and the included 2.25" silicone couplers let them work with a stock S4 Y-pipe. Wire-reinforced high-temperature silicone prevents collapse, the hoses keep provision for the factory bypass valves, and hose clamps are included.
