Integrated Engineering Performance Cast Downpipe - Audi A4/S4/RS4 B9 / A5/S5/RS5 B9

This Integrated Engineering downpipe replaces the restrictive factory item directly after the turbocharger, where exhaust flow matters most. Opening up this section lets the turbo spool sooner and breathe more freely at high load, and it's one of the most effective single upgrades on a tuned car.
