i love the truck, i wanta do a cai and a cat back. witch ones are the best, i was lookin at jba, afe, kn, n banks but cant decide. n is there a way to lock the rear dif with out 4x4 engaged. and any other hints would be helpful.
I got a K & N in my truck and I can definitely feel the power and an improve on gas mileage. For this exhaust, I got a banks exhaust and it works well. I think that Banks has one of the best systems for the titan. Also, get a THROTTLE BODY SPACER, it gives you low end torque.
