Advice for Cats

[gbowles at cansafe.com]

I'm asking for a friend. He has a 2004 S4 4.2l with 4 cats (as I understand what he said). He is in the process of having the exhaust modified to achieve a sound more in keeping with the beast under the hood. Someone has recommended removing the 2 rear-most cats to get that. This is in addition to replacing the system from the cats back. His question: Is the car likely to pass emission testing if that is done. If so, is it legal. (Passing the test is the bottom line after all.) Any BTDT and/or recommendations appreciated. Thanks.
