All I'm saying is that making real power gains on this 5.7 is a rabbit hole. I like those headers. I don't think I would use that exhaust. I'd just have a 3" made at my speed shop so I can pick and choose my muffler... Probably a Borla or a flowmaster...
Let me just get this straight to make sure im understanding you correctly. Are you actually saying its not possible to make any power gains with the 5.7 or are you saying that the headers in the original post wont make the claimed power output. PLEASE clarify.
