SIPLOWGUY Posted September 21, 2020 Share Posted September 21, 2020 I am replacing the original exhaust on my 1980 Cadillac. Yes, that's right, the original! I noticed the heat shield on the catalytic convertor is hanging. I foolishly pulled on it but it isn't as loose as I thought and didn't come off. I will be securing it with steel wire for now but I want to replace it. Seems the GM pancake converters are no where to be found. How would this affect AACA judging? Would an aftermarket cat be acceptable, or removal of the heat shield? Link to comment Share on other sites More sharing options...
