Thats a 5.3 exhaust, 6.2 has a small resonator can after the axle hump and the tailpipe goes straight out under the bumper not angled behind the wheel. You could say Im somewhat of an expert on the 6.2 exhaust

EDIT* Silly question, is there a difference in length from the Y connect on a ECSB? I have a RCSB
