Can you change header pipe & slipons now & this winter do the rest stage one. Or is it best to do all at once on a 012 Ultra 103

 

Yes you can, but why do only half?

Well if you do that the only other thing left is the breather to finish. Why wouldn't you just go ahead and do that as well? Let it breathe!

 

I did it without any problems when I first got mine, until you add more air with a different air cleaner you won't have to mess with the tune. I didn't have the $$ to do them at the same time either, so I waited and did the a/c and tune a few months later.

 

You can get a K&N element for the original AC. That us what I did when I put on my slipons

 

yeah what he said, but the tune makes the heat go away when you remove the cat

 

I did mine the same way, you do it when you've got the funds. If you don't want to do a fuel manager you can go with a VIED or XIED but you'll have to do one or the other to bring in more fuel or it will run real lean.
