One set of slip-ons for another, I think you're good. If you put them on and don't like how they work(decel pop) then you will need to address the tune. Do you have a fuel tuner yet or just maybe a Stage I HD flashed map?

Pretty much an "even-steven" on this one so you should be good to go. If you were adding a a/c swap in the mix...then I'd get a tuner, or download/adjustment.

If I were to pick sides, the S/E II's are probably slightly more restrictive. That may enrich the fuel mixture slightly. If it still runs good leave it alone.
