I was gassing up and heard this manual extend cab extended bed Ram Cummins Turbo Diesel. Looked like a 98-2000? This thing sounded like a big rig, like a Jake Brake when he was downshifting and all. Had a better sound than I am usually hearing. He had what looked like a Stainless Steel sewer pipe comming out the end big double tube rollbar with 6 KC's dual CB antennas hanging there too and a large brush bar on the front. So what did he have giving it that extra big rig sound. I have been looking at getting a Ram CTD for plowing due to its fuel econo and being able to run it as long as I want keepin' me warm while sleepin. What does that all do for performance and how much$$ are we talking?
