its a simple install. just a matter of how rusted the botls are. it helps to have an extra set of hands or two just to hold things in place while another person finger tightens a bolt. everything will bolt up to the stock cat, so that wont be any problem at all. just be prepared to loose some low end torque. mid to high end is much better though. when selling my 5th gen accord and taking off the i/h/e it felt like air could not get out and everything was so restricted. you will feel a difference. air flow is just a lot smoother. don't expect HUGE gains by any means. just an increase in responsiveness and a little mid-high range power.
