what would be a good first mod on a 01 ram 4x4 ext cab with 5.2 v8

 

K&N FIPK II kit... then exhaust, single in/out or dual 2.25 out (helps keep low end torque). then a programmer

 

You'll see the biggest improvement using a programmer right off the bat, they're designed to show the biggest improvements to HP and Torque with the stock setup. However, I did the AEM Brute Force Air Intake, Sony head unit, MSD 6AL Ignition, SS Blaster Coil, 1200W sub replacing the center seat, 8.5mm wires, NGK Plugs, Brush Guard, and finally Rockford Fosgate component speakers in that order. I suggest any of them =)

 

Oh yeah, forgot the Flowmaster Super 40 muffler and exhaust. Loud as heel, and helped snap my neck back in the seat too.
