Reason I'm selling is because I'm giving my G35 Sedan to my girlfriend and she does not need and will not notice any mods. I just took these off last week and I did notice that one of the cat elements is loose inside the chamber. The element itself is not broken or distorted in any way. I called Berk and spoke to Brian who told me this is a common occurrence and there is absolutely nothing wrong with the HFC and nothing to worry about. I have 8 bolts and nuts. I think I may be missing 1 or 2. You can get these at Home Depot or any hardware store. I am NOT including any gaskets but you can use RTV or just get new gaskets.
Retail price is $549 plus tax/shipping.

I want to sell them for $350 picked up. Of course add shipping if you don't live in Socal.
These are OBO!
