THE-Bi pipes are available for Rs4 and S4.
A reduction is welded on the bottom end of the S4 pipes so that the OEM tube and intercooler can still be used.
Therefore we recommend to use THE-Narrow fan set!
More throughput because of a larger diameter.

These items don´t burst open at the welding seam.
