Replace your restrictive OEM Audi bipipes with 034Motorsport's High-Flow Stainless Steel Bipipe Set for the 2.7T! Eliminate a major bottleneck in the 2.7T motor while improving boost response.

Engineered utilizing CAD software to ensure perfect fitment and optimal flow. Manufactured from precision mandrel-bent 304 Stainless Steel to minimize heat transfer from the engine bay to the charge air. Constructed utilizing 2" diameter tubing with flared ends to mate up snugly with OEM or aftermarket intercooler outlet hoses and throttle body boots. Each bipipe features beaded ends to prevent hoses from blowing off under boost, and 1" nipples for diverter valves (stock is 3/4"). "Stealth" water-methanol injection bungs are welded underneath each of the bipipes to accommodate WMI kits.

034Motorsport bipipes are designed for direct bolt-on installation, and can accomodate upgraded intercoolers and electric fan kits. Fits all 2.7T equipped B5 S4, C5 A6, and C5 Allroad models.
