I ran the SE 1 7/8" on my 16 SS and my 16 C7. They fit really well and sound awesome, mine were catless with the SE Xpipe. I would go ahead to get one step colder plugs, buy the 12" wires so you can keep them off the headers, they build their own wires and are really high quality. I think only the drivers side needs the extension. Buy some header wrap and wrap the tubes closest to the starter. Wrap the starter also since the headers will create a lot of heat and may kill the starter at some point so don't take a chance. If I remember correctly the starter heat shield will go back on with the long tubes so that's where the header wrap comes in. Good luck and get a tune.
