Ill do u a favor right now an say u will never pass EPA noise test with just a oem axle back, Swap the whole system minus the headers, last thing u want to do is mess around with ur current system just to pass a test wen u coulda just swapped over ur cat-back+cat back to oem an pass with flying colors...
Headers dont contribute to the overall noise level, so just leave it as it is, but like i said, just swap out ur catback an cat to oem an u should b sweet
