Just bought a 2.5 turbo Titanium x Mondeo. I believe it has the same engine as a focus ST?

What can be done performance wise with them? I cant find an induction kit, only a replacement panel air filter (bore off lol)

I see evolution chips do a remap releasing a few hp and lb/ft but is that all that can be done?

I wouldn't mind being able to actually hear the 5 cylinder growl either so is there an after market cat back exhaust system available? My 535d BMW sounded better than the mondeo at the moment.

Cheers
