Hello everybody ! I'm new to the forum and have already found lots of useful info . I just received my new CGS cat-back system that was listed as fitting an 07 Titan Crew Cab , but when I opened the box , SUPRISE ! The muffler had a single inlet with a single outlet . The factory muffler has dual inlets with a single outlet . After talking to the guys @ CGS , they suggest that the exhaust system on my truck is from an 08 . The production date on my truck is 12/06 , and the 10th VIN character is a 7 . I now have the correct system on the way , but I was wondering if anybody else out there has run into the same problem ?
