What does Downpipe Decat, Euro 3, Euro 4 and Euro 5 – 200CPI, 100CPI 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.

100CPI= Less cell density than 200CPI, better flow, but less emission cleaning. Not street/road legal.
