I have an 07 with no support bar and the heat shield looks burnt through + loose. with the winter coming should i take that off incase a chunk of ice decides to rip it off with that $150 o2 sensor?

All of it. I know it's a problem and will take it in for evaluation after the holidays. Never any codes and very few misfires according to Torque. I bought it with only 10K miles on it and never knew it had a problem until it recently picked up power. It has 27K miles now. Weird.

Could be. I pulled the front of the cat down a few months ago, and it looked perfect. How does an RX-8 cat typically fail? Does the front catalyst stay clean, while the rear catalyst clogs? How does one inspect the rear catalyst with the resonator in the way? Bore scope? Anyway, I also had the stealership inspect it, and they told me it was normal and charged me $120 for their trouble.
What caused me to suspect it might be bad was stronger than normal odor, a hissing sound under the hood that sounded more like a slight exhaust leak than a vacuum leak, and a putting sound in the exhaust that occurs about every 10 seconds.
No one has ever been able to find the "leak." The putting sound is supposedly normal according to what I have read on this board. The cat is supposedly OK.
What really remains unexplained is where a whole lot of extra power came from the last time I had the car on the track.
Since I am thinking of selling the car, I will take it to a different dealer for another cat inspection and compression test to see if I can find out what is really going on with the car. I'll do this after the holidays since my 8 is not my daily driver and mostly just sits in the garage.

I called another stealership today, and their service guy told me they test cats by doing a sniff test. If it passes, it is a "good" cat and will not be replaced under warranty. They want $115 for the pleasure of testing it. When asked about a clogged cat that can pass a sniff test and also destroy a rotary engine, he had nothing to say.
I can't feel good about passing a cat problem on to another owner, so I'll have to figure something out.
Of course, all decisions hinge on how much I like the MSM, which should arrive tomorrow. The 8 could end up with a BHR midpipe and be thrust right back into service.

Just to complete my hijacking of this thread, I pulled my cat and inspected it tonight. An ultra bright flashlight was shoved up its butt, and I rolled the cat around so I could see the light from every angle through the honeycomb. I found absolutely no evidence of any clogging. It is a nice shade of red on the outside, though. This is a good cat.

It's just the picture size and distortion from the cell phone camera lens. There are no signs of foreign matter at all. Here are a couple of huge shots from slightly different angles.
[Regardless, my next purchase will be a BHR midpipe to remove cat failure from the equation in the future.]
