    2009 sts 4.6 awd exhaust ?

    i,d like to put a gibson cat back exhaust on my 2009 sts 4.6 awd but cant find any specific info as to weather or not it will fit , ive called gibson , and theyre not 100% on the fit but are telling me it should , ive also got a call into the dealer , but havent heard back yet. im pretty handy with metal fabrication so i dont need it to be super easy , i can definitly make things work when need be , unless it,s just a completely diffrent system . from the researching ive done it looks like people are using the sts-v setup and are installing on regular rwd 2008 sts ,s, but i havent been able to find anything on 2009 models let alone the awd aspect of it . did the pipe diameter change between 2008 -2009 ? anybody have any experience with this application , thanks
