Bump to old thread, getting the p0420 code and not so great mpg, which I have searched.... but want to know the following....
A) Which 'off-brand' cat converter did you get?
B) How long has it been in trouble free service?
C) Are you happy not going OEM?
D) Do you have a dual cat setup? (specify if you have cal emissions)
thanks
