Overview
The COBB 3" Cat‑Back Exhaust for the Ford Focus RS is a direct‑replacement system built from full 304 stainless steel. It pairs a straight‑through resonator with a performance muffler and integrates an OEM‑style electronic exhaust valve, so there’s no need to transfer the stock unit. The valve plugs in and works with factory drive modes, and is fully compatible with COBB OTS maps or custom tunes.
