So I decided to get it along with some ERZ HFC's and got them installed!
The ERZ HFC's are great. Fitment was perfect and the quiality seems real good. No issues with them at all and no CEL light so far. And for $369 shipped, you can't go wrong!
I had heard about the horror stories about the dreaded demon bolts. But little did I know how much of a pain it was going to be. The driver side demon bolt was the worse though. Took me and a friend over 4 hours to remove just the driver side cat alone! For a while there it was not looking too good! Thought I was gonna have to limp to Midas to have them take a stab at it! But in the end I was able to get it off! (Though through drastic measures!) Had to cut the cat in half and pry the end open enough to get an air chisel in there to break the bolt! Amazing....
