COBB Cat-Back Exhaust - Ford Focus RS (LZ)
The COBB cat-back exhaust is a direct replacement for the factory cat-back on the Ford Focus RS (LZ). It is built from 76mm (3") 304 stainless steel with a straight-through inline resonator and muffler, finishing in dual 114mm (4.5") polished, double-wall slash-cut tips. It comes with the same factory exhaust valve already fitted, so the drive modes still switch between an aggressive valve-open sound and a quieter valve-closed setting.
Note: Compatible with the factory or COBB downpipe. Installation by a professional is recommended.
