Ford Focus ST Mk3 3″ Performance Downpipe Exhaust

Downpipe exhaust to fit the Focus Mk3 ST. This is a 3″ downpipe and fits from the turbo to the cat. It can be fitted either with the OE cat or to a 3″ sports cat or decat. Fitting this will reduce turbo lag and significantly increase power, a 3″ exhaust is easily capable of flowing 400BHP so you have lots of scope for future mods. Comes exactly as shown in the pictures. Direct fit, should require no vehicle modification. We would recommend having the car remapped after fitting to optimize the higher flowing exhaust.
