New Pipes and Stage 1 2011 Ultra

[HD_2011_UC]

I am planning doing the stage 1 kit and new pipes this spring I am looking for bettter performance, full new exhaust rather than spip ons, a nice looking set of true duals with a deeper throaty sound, compared to the stock exhaust. I also want to keep the sound within legal limits re noise laws in Ontario Canada.

Looking for suggestions on new pipes? Also, is a dyna tune required once the mapping is complete for the ultimate best performance?

Thanks

You will need a tuner and need to have it dynod for best results
