People who want to pass yearly emission tests need to keep their SAP.

Those who choose to install things like catless headers tend to remove SAP as well as it simply become useless to them.

It all depends on where you live and what are the regulations for emission tests in your area.

In my area I 'm forced to undergo emission test every 2 years and if I want my car to be road legal I must have SAP at the time of the test.
