Catalytic converter ?
Just yesterday my ML430 started having a fluttering/air sound coming from under the vehicle and a slightly noticeable loss of power. It sounds like its coming from one of the cats. Anyway, if its a crack in one of them would you guys have it welded or would you just go with the Magnaflow cats (its only like 80 bucks a peice) and just go ahead and get 2 of them and replace both?
