So i am getting my bikes 416 kit and hot cam installed, and was wondering if i need to put a new header pipe on it. i have the white bros slip on and yea

 

so anybody got an answer?

 

You can run the stock header. You would get more gain, out of a full system, but not alot. If you have the E series slip on, I think you would need a new muffler. I don't think the E series I had would go on the White Bros. header.

If you aren't getting the head ported save your money for other mods.
