Hi I am hoping someone can answer this for me. I want to buy Flowmaster cats, but they are only listed up through 2009 Chargers. Is there any change after 2009? I am 99.99% sure the 2011 has the same cats, but I can't seem to find out for sure. I looked up Kook Cats and its the same part numbers for 2009 and 2011. I really hope I can get an answer. Also I am going to get a set of Flowmaster Scavenger Elite Shorty headers as well. Anyone have any opinions on those? I want to keep car street legal so i am not looking to eliminate the cats or go with long tube headers. I already have the Flowmaster American Thunder Cat-Backs and love it so I would like to have the entire system Flowmaster even though I know there are cheaper headers.
