It wasn't setting any codes before I tore it down and I had just finish a 10,700 mile road trip in it. Any constructive input would be greatly appriciate. Thank you gentalmen.

I'm not disputing GC's statement as he actually went thru broken cats w/ his Z. But at BG this yr a brother had an ignition coil go out and you should have seen the glow at night....due to the unburnt gas from those cylinders...man they were a light show under the car. Just saying couldn't that circumstance provide temps beyond the melting point of the bricks?
