Talk to the guys at the muffler shop, they know what is available. I ended up putting a High Flow Cat and Magnaflow muffler on my old Z71, picked up about 3MPG and sounded great. My Ram doesn't have 1000 miles on it yet and I need to inquire about warranty (I have 80,000 bumper to bumper and lifetime powertrain) if it doesn't void my warranty I will add the same to this truck.
