Just bought a '14 Express Blackout and I want to put a Flowmaster 50 on it (have it on my 4.7 '02 & love it). I haven't taken delivery yet but I want to have the muffler ready to install when it comes in. So I have a few questions, the first is what size inlet/outlets is the exhaust pipe and the second is will changing the muffler throw any codes or issues. Any help/advice is appreciated. Thanks.
