Finally a proven, high-flow downpipe solution for your B5 S4 2.7T. The ar design 3" downpipes increase the diameter of the piping almost 1 full inch over stock downpipes, making them the largest tubes that will fit on the S4. Not only does the increased 3” diameter minimize backpressure to allow for quicker turbocharger spoolup, and free up horsepower (over 30awhp gains on a PJK04 S4 from “piggie” pipes), they also add an intoxicating, aggressive sound. The optional race cats further reduce the flow restriction caused by the stock catalysts.

You can opt for either high flow race cats (emissions friendly in most states) or test pipes (no cats) for off-road and track use. We also offer a V-Band setup that allows you to swap between test pipes and high flow race cats in just minutes.
