Welcome!
Your truck, your choice.
YouTube is full of RAM 1500 exhaust clips.
You can go from cheap welded in to whole systems from the back of the catalytic converter--even a muffler by-pass or muffler delete kit.
Remember: your goal is to make it sound like a Hemi, not raise the dead. Bottom line is the factory muffler is too quite, too big and too restrictive,
BUT it is possible to go too far, and its really a matter of where you live and drive and how close the rest of humanity intrudes on your exhaust volume--just saying.
