THE- RS4/S4 B5 cast aluminum bipipes

Product information:

THE-bipipes are made by aluminum casting process and all connections are CNC machined. These pressure tubes are specifically designed for the RS4 B5 bodies. With an S4 body, the "folds" must be folded / machined on the side member (see pictures as with OEM RS4 side member) to ensure the free movement of the tubes. The mounting points of the brackets are selected so that a mounting with RS4 and S4 timing belt covers is possible.

Advantages over the OEM part:

• More throughput due to a consistent, larger diameter
• The flange is screwed 2x and has a larger diameter at the support to the O - ring (sealing surface)
• no weld seam at all therefore the bursting of this is excluded

Additional information:

• To avoid problems with the OEM fan wheel, we recommend using our fan set as well:
  • THE- Narrow fan set
• For vehicles with S4 intercoolers we recommend our silicone hose:
  • THE- Silicone hose RS4 pressure pipes - S4 intercooler
• For easier assembly of the diverter valves:
  • THE- silicone hose kit for bi pipes to diverter valve 70 degrees

Scope of delivery:

• left and right bipipe
• all needed screws
• Retaining bracket incl. mounting material
