Cat Convertor Goes Boom

![Unhappy](https://www.rx8club.com/images/icons/icon9.gif)
The other day I noticed a weird metal noise when hitting the gas or breaking hard, accompanied by a p0420 CEL.
I’ve decided from some searching that what I’m hearing when i hit the gas or stop very fast is pieces of my cat ( the shards of broken ceramic?) moving around in my muffler? Not sure where these pieces have gone.
Anyway, I need a new CAT. What’s the prevailing thought on just getting an aftermarket midpipe versus the OEM. Search has informed that this is often a cheaper option, but what’s the downfalls, and what pipes are people using?
Also can I just take my CAT off and run without one until inspection time rolls around?
How much damage is currently being done. Had to make an emergency 500 mile trip this weekend due to a family death with the car in this shape. Interestingly I got 21mpg and the car seems to run fine? Possibly a little sluggish.
So basically my question is. Did I diagnose this correctly? What’s my cheapest option. 2004 5 speed 85,000 ( hurray for missing out on the 80k warranty)
Not looking to spend $1500 on a car worth 7
Thanke

Yes, you can get a midpipe until inspection time or you can get a high performance cat pipe from either rx7.com (Rotory Performance Supercat), http://www.rx7store.net/category_s/300.htm, http://www.corksport.com/corksport-p...e-for-rx8.html or http://blackhaloracing.com/products-page/exhaust/ .

alnielson- I live in Clifton Park New York. Yourself?
Do you think I Correctly identified the issue?
Does Something like this fail inspection?

The Racing Beat part is a resonated midpipe. Not a catalytic converter pipe. The links I gave you were for a cat pipe which would be much cheaper than buying one from Mazda.

So the corksport piece or the rx7store piece would pass inspection?
Is that all i would need to purchase to replace the CAT. I guess im just confused because I cant understand why the mazda part costs over $1000 and these come in at $300.
Interesting.

Where is here? Do I in fact live near you?
The difference between the Cocksport single resonator and dual rsonator is only related to decibals? Or is there more to it.
Thanks for the help!

Hey nycgps thanks for contributing nothing! but i hope for both our sakes you got some amusement from your really really funny Google link. I couldn't stop laughing and realizing how dumb i was..... I mean I suppose the real question is why bother even having active forums these days, Google in fact has basically every question covered regarding almost any topic. So lets just lock up every forum on the internet as its 99% of the time just a rehash of the same information.
Seeing as it was already covered that midpipes would fail inspection, the new question was whether the high performance cat pipe from rx7store would be a good solution to replacing the cat, passing inspection, etc etc.
Thanks

You need a CAT to pass inspection. simple. doesn't matter what kind of CAT.
but would the cat last? Search button up there ?
Forum is a place for information, its for people who is WILLING to find them, not for people asking the others to "spoon fed" their sorry *** with info.
