Hello: I have 06 WRX with 20 g turbo and all supporting mods, including cat delete. Cobb AP has suppressed any error codes pertaining to emissions, but was wondering if anyone had experience passing vehicle emissions testing. Thanks in advance.
Some places check for a cat and some do not.Other than that you should be fine.They will prob. just hook up a connector to the obd/dlc port and check for codes and readiness monitors.
