I ordered some Big Growl exhaust and was wondering what else I need to install. It comes with mounting hardware but do I need new O rings or new exhaust flanges? Also, to prevent chrome going blue, can anyone recommend a product to put inside pipes to protect. I've heard of Blue Shield but I know there are others. Thanks in advance!

 

Get some new Screamin' Eagle exhaust gaskets and you can reuse you exhaust flanges from your original pipes.......Then add some star locking washers or aircraft locking nuts when you put the new pipes on. Search for a thread on here about loose/missing exhaust bolts.
