Just acquired an '09 Grand Marquis and was wondering if anyone has had experience installing a dual exhaust system on the '08 and up models. I know the hangers will have to be installed but is there any other reason a system like magnaflow's cat back (for the '07 model) will not work? I'd appreciate any advice!

I don't think there should be any issues. You might call magnaflow and ask them directly just in case though.

 

they should work fine
