I had a shop install the Cat Back American Thunder system on my RAM, 5.7 Hemi. This was a "replacement" for a system that came with the truck when purchased used. My son and I can not get over the marked difference in sound and performance with this new system. It is like driving a new truck. The engine runs smoother and operates like it has another 40 horses under the hood! At idle, the sound is barely noticeable in the cabin. Acceleration is the sound of new power. Great purchase!!!
