Since they're made of platinum, they should taste like money.... lol....
Brought car in to my AMG tech because I had brought it up to Eurocharged for a dyno tune. Ran really great for about 4 hours on the way home, then started misfiring and running like crap. Found the catch can was completely full and I'm sure was spitting into engine. Everything else checked good. Emptied can, changed plugs, AMG tech took for a drive, still not making good power. Brought it back to bay, revved up the engine and walla - cat pieces everywhere... At least we know AMG makes free flowing exhaust systems! I'm glad I had my secondary cats out..

So the cats were from ROW racing. I talked to them and they said there only supposed to go after the headers in a secondary cat position and not to replace the primary cats. Wish I had known that before spending the money to buy them and get them custom installed 
. On the brighter side, my exhaust got pulled off, all the remnants cleaned up and out (like a roto rooter) and now I have a free flowing catless exhaust with factory manifolds. Really not too much louder, they were only 200 cell cats to begin with.
