This Ford Focus ST Mk4 performance exhaust is made in 3"/76.2mm pipework and fits from the downpipe to the centre section, replacing the GPF exhaust section.
This exhaust makes the system louder as it removes the GPF filter and therefore, offers a significantly sportier exhaust note.
All relevant fittings and gaskets are supplied for fitment.
Fitment will require basic engine tuning at time of fitment to cancel the EML light.
Fitment is for motorsport and off road use only.
The product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product.
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
