The ST170 Cat Back System from Milltek Sport is the class leading Exhaust for the 170.

Owners of Mk1 Focus ST170 models can now enjoy the benefits of a Milltek Sport stainless steel sports exhausts system. Designed in-house and developed using a state of the art rolling road, this Premier Quality Focus ST170 system is hand-built by British engineers at the company's famous Ilkeston research development and manufacturing Centre.

With huge experience designing exhausts and manifolds for some of world's top Motor manufacturers- Aston Martin and BMW to name just two, Milltek Sport staff know what's required to produce a performance exhaust that outclasses the standard item in every area, providing a rich, mellow exhaust note without being unduly noisy.

Designed for all Focus ST170 3 and 5 door models from 2002 onwards, the new system is produced from aircraft quality T304 stainless steel throughout and utilises a single round 90mm tailpipe with a slashed rolled inward tail that sports a discreet engraved Milltek logo. Thanks to performance designed internals back pressure is much reduced although not fully eliminated to retain torque compared with the standard system, which aids power and improves the exhaust note.

The Milltek Sport Focus ST170 sports exhaust comes with the peace of mind
