So, I have my HFCs waiting in my garage to be installed. After calling several performance exhaust shops, no one wants to install them. They say that the stock cats have the same guts as the HFC and there really isnt such a thing as HFC and that they will cause more problems than whats its worth. Also, that they are all made pretty much by the same cataltic manufactures and im just wasting my money. Is there any merit to this? Ive read tons about them from this site, i just want to know where they are coming from? I mean, if everyone is seeing results, then i'll take proof of gain over what some guy says, im just wantng to know where they are coming from on this?

Thanks, i just need some clarification!
