I have been trying to order a exhaust for my titan. I spoke with Banks about the Monster Exhaust and they said that they have not had any 2010 or 2011 titans in there to see if the 2004-09 fit the newer models. Has there been any changes that would stop me from just ordering the 09 Monster and bolting it on to my 2011 pro-4x??? If I can't are there any other exhausts out there that you guys would recommend?????
