Hey man! This is Sheiss D. Ryan. Glad to see you're on this forum!
I'm willing to bet that these headers are the way to go. I have an 05 5.7 WK, and put on some 06-10 SRT8 headers, but they were a massive pain in the arse. Had to cut out the reso's from the headers and weld in new cats, which had to be the right ones, or they wouldn't fit. Had to find my own O2 sensor harness extensions and supply them to the shop, the list goes on. It was expensive and frustrating. If I were to do it over again, I'd get these headers and then a nice catback. As it stands, I have a dual Flowmaster 50 setup that sounds sick, but if I had waited a few months and gone with these headers and a catback, I would've spent about half as much.
