What does Downpipe Decat, Euro 3, Euro 4 and Euro 5 – 200CPI mean?

Deca= No catalytic converter at all (more power, not street/road legal).

Euro 3 / Euro 4 / Euro 5= Emission standards that the catalytic converter meets. The higher the number, the cleaner the emissions.

200CPI= "Cells Per Inch" i.e. the cell density in the catalyst. 200CPI is flow-friendly, but cleans less than, for example, 400CPI.

Downpipe Decat

Maximum flow and power

Downpipe Euro 3 – 200CPI

Downpipe equipped with a sports exhaust system with light emission standards.

Downpipe Euro 4 – 200CPI

Balance between emissions and power.
Suitable for street and light tuning.

Downpipe Euro 5 – 200CPI

The strictest emission standard – but still flow-friendly.
Suitable for newer cars and responsible tuning.
