I have a 2014 DD limited and am looking for a r/t exhaust so that I can do the dual exit conversation. If someone has one in Washington state that would be super cool.

I'm looking at different options for dual exhaust. I have a 2007 SXT with a 4.7L in it. Anybody have advice on what to get? What does everyone think about headers? Are there any downsides to installing headers and dual exhaust? Do I need to do any fine tuning to the engine or system after...
