Will this replace the cat?
Do I have to lift out my engine to get it in?
How much work is required to install it?
What might it cost for me to pay someone to do it?
How much of a HP gain can I expect when I still have stock exhuast?

From what I've read you might get 5hp and no, the greddy dosn't replace the cat, i dono about anything else.

It's not a hard install.  The hardest part is probably getting the heat shield off along with the stock manifold.  The greddy header is an easy fit.  Cat stays where it is.  You may have to pay someone over $100 to have it installed.  If it was the hotshot header, I would have someone else install it, if it has anything to do with replacing the cat.
