1) If I do the EGR blockoff, will I be able to pass emissions with my stock catalytic converter system? I'm putting in a DP, but might need to replace cats for emission testing.

2) At what psi level will I need to be concerned with adding the EGR blockoff plates? I plan on running 15 psi for a little while, then upping from there.

Thanks in advance.
