Hey everyone First time poster, im new to the titan world and computers so please bear with me.I just bought my first Titan. I'ts an 07 crew 4x4 and i am totally stoked. I love it!!!!I'm looking for suggestions on cat back systems. Every sight I go to has them for the 06 and earlier but not for the 07 with the dual pipes to the muffler with 2 inlet and 1 outlet. I don't really know much i'm just learning about Titans but i'm ready to get into it and would appreciate any help anyone would be able to offer.
