Hey my OEM cats are starting to fail now and figured if im going to replace them might as well try and upgrade as well. Looking for used HFCs in good working condition. Brand doesnt matter to me so much as at this point anything will be an upgrade from these. Looking to Spend $350 Max depending on the HFC.. If anyone has one or knows where to find one please let me know. And yes i know i can buy new Kinetix ones for just a bit more but i figure that a used set of berks would be better than new Kinetix or CNT. If im wrong on this sentiment please someone correct me. Thanks
