034Motorsport Bipipe Set, B5 Audi S4 & C5 Audi A6/Allroad 2.7T, Stainless Steel with WMI Bungs
034Motorsport's stainless bipipe set replaces the restrictive factory bipipes on 2.7T-powered B5 Audi S4, C5 Audi A6 and C5 Allroad models. The brand says the larger pipes remove a major flow bottleneck in the 2.7T and improve boost response. The pipes are mandrel-bent from 304 stainless steel in 2" diameter to limit heat soak into the charge air, with flared and beaded ends that seat snugly in factory or aftermarket hoses and resist blowing off under boost. Each pipe also carries a 1" diverter valve nipple, up from the factory 3/4", and a discreet water/methanol injection bung welded underneath.
