The mountune GPF-back exhaust for the Mk4 Focus ST adds a noteworthy boost to audible performance, reduces back-pressure and enhances vehicle aesthetics.
Constructed from 304 stainless steel, the 3" bore system improves vehicle performance - particularly once power output has been raised, thanks to the low back-pressure design, whilst the carefully engineered internal muffler ensures this system remains free from intrusive cabin boom, whilst delivering an addictive soundtrack.
Also available with either a polished or carbon fibre trim option to suit your individual preference:
