When I bought my car it was discovered that the converter is hollow. I wonder is there any performance difference if your converter is hollow? Any downside other than environmental? Not that I am advocating converter tampering......my car was purchased that way. I wouldn't even know how to hollow one out. Can a converter fail and break apart inside and "hollow" out and not know it? We do not have any smog type checks here in Maine so it doesn't effect my registration or inspection as it appears to be "normal". I have it on my list of things to do at some point but for the last 7 years I've had no issues. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
