you don't "NEED" to remap for just slipons. It can't hurt though.

You only NEED to remap when you change intake and/or headers. It's the intake and catted headers where the air flow gets choked up.

You should have kept reading. Retuning accomplishes nothing with slip ons.

Retuning can yield mild performance improvements even on a totally stock bike.

Well to post an update I ended up buying a Cobra Lo-Boy Staggered full exhaust, a lot like their Dragster model but 2 1/4'". It was a sweet online deal so I ended up calling Cobra up to find out more about them and the guy said they haven't been made in about a decade but some places still have a stockpile of them. Gonna be 45 degrees here in Central NY on Saturday so Im gonna try and get them on and maybe ride if it isn't raining. Hoping I dont get any popping but if I do I'm eyeing the Cobra PowerPro Black Tuner...
