I understand the headers don't have a cat in them and it is in the mufflers. I put on a set of Rush slip ons and been thinking about doing a stage on.
is there anything wrong with using the stock headers? your thoughts Please>

 

not at all. But there's better flow from a long 2:1
I got the Rush. Like it. Slightly nostalgic lookin, but not nostalgic enough. Need fish tail
Look at the vance and hynes for a tuner and DK customs for the cleaner. Fuel moto has a nice cleaner too.

 

I just put a 2-1 Vance and Hines Pro Pipe on my Heritage. The stock header would work fine, but I liked the look and performance of the different system.
