I installed the Cat Back system - American Thunder a few weeks back. I was fun scaring the neighbors with the sound of the 5.7 liter but the drone between 1700 - 2000 rpms finally got to me. The resonator killed the drone and muted the cat back to some degree. Although Auto Anything claimed this to be a "button up" installation, it really isn't. You'll need to cut into the existing system and I recommend having it welded by a reputable shop. Nice mellow rumble now.

This was replacement muffler for catback system bought 4 years ago. The inlet pipe of muffler rusted out after so required replacement. Muffler is well built and has good throaty sound at idle and under load but is more mellow at cruise.
