KMS Motorsport Cat back Thunderstorm Exhaust - Focus Mk2 ST225


This KMS exhaust is made in house with T304 stainless steel, mandrel bent and mig/tig welded.

The system is made in 3 inch/76.2mm pipework. This part replaces from your catalytic converter back.

Tail trim options, for the ST225 4.5 inch or 5 inch slash cut, 

A centre resonated box is available at extra charge if required.

Videos available on Youtube and our Facebook page.

Your standard exhaust will require cutting to be removed, this should be carried out by a competent person.

This KMS system will enhance exhaust gas flow, reduce restriction, improve sound, performance and driveability and allow the car to gain more POWER!

The decat/sportscat may bring on your MIL (Malfunction Indicator Lamp) unless you have stage 2 software.

Please Note: An exhaust system without a catalytic converter will NOT pass a UK emission test/road side check and therefore it is not intended for road use.

Due to the popularity of our exhaust systems, stock may fluctuate - please note we do endeavour to build a system within 10 working days if not available.
