Cat replacement

[Steve87GN]

So, lately I've been hearing a little bit of a rattling from underneath the car. I crawl underneath and everything looks fine, but I started her up and got under again...and its coming from the cat. Looks like the ATR cat that I've been running for 8+ yrs. lost the brick, or rather the brick has come loose and rattling around from the sound of it. So, is there any specific cat you guys would recommend as a replacement? I was thinking about this one from Magnaflow at Summit...

Thanks in advance.

I believe that is what I am running, but mine came from Red Armstrong at Quad Air and was trimmed specifically to fit between a Hooker Cat-back system and a Terry Houston downpipe. Mine works great.
