In the lower rpms the car will bog and jerk rapidly and then once it hits like 3500 rpm I have the "turbo spool" sensation. My muffler hanger broke so I just took it off at the axle is that bad? It's done this before even with the tusdo muffler. Car is stock accept for custom short ram and catback. No cel on dash.

I think he is refering to the entire cat, not just a o2 sensor.

Yes, because the rear o2 sensor would pick up the failure of the cat.

My SS had 2 Cat's on the DP. Just get a new DP with a high-flow cat and you'll be fine. It's much cheaper than trying to pay for 2 cats to be replaced. If your secondary Cat is bad, it's because your primary is bad too. If it's just the primary, that means your 02 sensor could go out at any time. It's better just to replace fully :)
