Factory exhaust limitations.

[captaudi]

Happy Saturday,

What is the limiting factor on the factory exhaust? My current setup in a Vance and Hines SS2R, Hank Scott jet kit and 5 deg ignition advance. Bike runs absolutely awesome. My plan is the aviationfred formula of factory downpipes, Black Widow collector and Dominator mufflers. His setup will allow me to either mount the Krauser K2 bags that I have or a set of Hepco Becker Juniors. I have a set of factory downpipes and a factory collector coming from eBay. Do I need the Black Widow collector? or is the factory part not a restriction? I saw something about the aftermarket collector being of a questionable grade of stainless. If the factory part is not an issue I may bead blast it and use VHT or similar paint. And yes the header pipes will be polished. The plan for next winter after child support ends is either 1350 or 1380. Whatever I do needs to support that.

Inquiring minds want to know.
