I recently purchased a cat-back for my Fiesta mk5 Zetec-S. Cannot fault it, looks and sounds perfect!
Milltek has already completed development of a 3-inch full turbo-back exhaust system and were so blown away by how well it worked in conjunction with an ECU remap that they decided to add one to their own fleet of high-performance cars which also includes the Audi TT RS, Audi S4 3.0 Supercharged B8, Audi A4 1.8T FSi B8, and VW Scirocco GT 2.0 TSI.
The car will appear as the main attraction on the Milltek stand at the Autosport International show at the NEC in Birmingham in January.
