Modern catalytic converters are not that restrictive. Why make the car street illegal, trigger check engine lights, and void your warranty for a few HP ?
The AMG exhaust manifolds are anotyher story. Rather than mess with the cats, just replace the manifolds with some good aftermarket headers like Evo, Renntech etc. Kleemann makes a very nice set of headers but I think they require sacrificing the primary cats, and really need the full Kleemann exhaust system to work at their best.
