Ford Focus ST170 MK1 2.0 Downpipe

63mm Downpipe without catalyst for the following models with 2.0 engines:

• Ford Focus MK1 ST170 2002-2004

Suited for versions with 170hp. 

By installing a larger bore downpipe backpressure in the exhaust drops which makes the exhaust gasses flow out better and increase horsepower at high RPM's.

By only installing a larger diameter downpipe the horsepower already goes up a few HP. Combining a downpipe with chiptuning brings even more extra power.

A software update (chiptuning) would be advised.
