As we all know there was a huge recall on catalytic converters for our cars. Well my cat clogged before the recall went out and so after gutting it and it being obnoxious I went ahead and bought a downpipe with a cat from zzp. So the other day just for ***** I called GM told them the situation and the guy said he will send me a form to fill out send it in with a receipt from zzp and they will reimburse me! So if any of you guys did the same thing as me call GM and try to get them to reimburse you it should work.
