i'm replacing the cat converter in my 2000 ES with a magnaflow. there's just one problem: i don't know if i need a bung for an O2 sensor. everyone i've talked to on my other car club says i need one, but they all have either a 2.0 or 2.4 and i have a 2.5. according to magnaflow's website, this is the cat converter that i need, as it has no O2 bung. however, i am told that i need a converter with an O2 bung, which would be this one. can anyone verify either of these statements?
