Yes we have state run testing centers. The exact procedure I am unsure of because the newest car that I own is a 73 Volkswagen. But I do have a number of friends that have V8's in their jeeps and off road trucks that were not allowed to pass or even to test because they have an aftermarket engine from a different manufacturer in their vehicle.
My opinion is that if an automobile can the test it should be able to be certified regardless of the modifications to it.
