Reduced Power Error

I have a 2006 M6 that I purchased last year (2013) from MAG in Columbus Ohio, I have the Error lights that display Increased Emissions, Reduced Power, Stability Control loss. I took the car to MAG to have the codes run after reading threads to have them checked immediately. MAG informed me the catalytic converters were bad and the warranty had expired 2 weeks ago, they would not honor the warranty. I questioned them why, I have driven the car less than 5k miles and the car only has 46k miles. The Service Manager quoted $19,000 to replace the exhaust system, due to the problems with the system. He suggested that I contact BMW North American and 3 months later BMWNA stated that MAG would not repair the car and MAG states that BMWNA won't repair the car. The dealer also made the comment the car is worthless until this exhaust problem is fixed. What suggestions do you have that are more cost efficient to have the car repaired? Please help.

Hello, let me see if I might be able to help you with your problem. First off two cats failing at once is very rair, did you happen to hit a very large pothole or bump? If so this could break the insides of the cats. Do you have a charging error come up on the display? If so this would have a problem supporting the air injector pump giving we your errors. I have had two alternators go out on two separate cars, one was a 2005 645ci and my 2006 M6. Both gave me the dreaded emissions error, once I fixed the problem the cars ran great. I hope this helps you with your car.
