Default Another exhaust question

Hey guys,
I just recieved a set of Rinehart true duals for Christmas, my question is this, can I install and run them without doinga flash to the ecm? Will this make my 08 Ultra run leaner than it already is?
I plan on adding a hi-flow air filter and SERT and dyno tune next month.

Personally, I'd wait until next month when you do the dyno run, SERT, A/C combo. I'm no tech, but I think they may tell you the same.
