Correct! I don't know why everyone (even Dinan themselves) keeps referring to it as OPF back but US spec cars have secondary cats, which are very different than OPF in terms of how restricted they are.
I guess it's easier to say "OPF back" than "secondary-cat back" lol. |
So does removing the secondary cats negatively impact emissions testing?
Also there isn't another set of O2 sensors back there, right?
