Hey NavySteve - What year model is your car? I've been cornfusing myself. The exhaust system drawing(s) online are the culprit. I think the drawings are correct, but I'm getting myself cornfused.
I'm back to thinking about yanking the 2nd catalyst. But when I pull up the drawings online I keep thinking, "yeah but there's only 1 cat." But actually there may be 2, because the drawing I'm attaching below IS SHOWING THE 2ND catalyst. This exhaust pipe attaches just after the first "monitored" catalyst.
I think I'm straight on that now ... but my post here is to ask you if you could confirm if I've got it correct now.
From left to right is, the 2nd cat, the muffler, then the resonator. No?
Thanks!
