Installation was not difficult, but took me 4.5 hours. I did it by myself, with another person it would have went quicker. Driver's side was a breeze, and the passenger side was a pain as advertised. The passenger side is very crowded and access to the bolts was difficult. Had to use a combination of different size wrenches as well as an open ended box wrench for one of them (Top front on passenger side). The banjo clamps at the rear were very simple. The o2 sensor wiring clips were a little fussy, I went slow to avoid breaking the tabs you have to pull out prior to unhooking the clips.

The ARH HFCs fit perfectly. The bend at the top by the flange is a little sharper than the stock pipes, so the bottom rear bolt is slightly less accessible. This is a great product! Thank you ARH! I would certainly recommend these!

I added the Big Daddies o2 extenders on the rear o2 sensor bung hole to avoid the CEL. No light so far, but it's too early to tell. If I do get a CEL I will update this page.

Here is the link to the o2 extenders I used:
