Flowmaster Universal Resonators Reviews


No more drone!

Reviewed By Dan L (CHELMSFORD, MA) Reviewed for a 2010 Jeep Grand Cherokee —7/8/2014 9:27 AM

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.
