Will these cars with High Flow Cats and Longtubes not throw a code with the STOCK tune? The reason for me asking is that from what I have read, with High Flow Cats the O2 sensors have to be turned off in the tune. This might lead to failing the OBD2 emissions "readiness" test, the only way to pass being to put the car back to stock tune and hope it doesn't throw a code with the high flow cats and headers. Is this true?
