Whoever said that getting there is half the fun obviously didn't drive with an aftermarket exhaust kit. The mind-numbing drone that seeps up into the cockpit turns road trips into torture sessions, which explains why people pull over to see oversized balls of twine and Paul Bunyan statues. Instead of putting up with drone, filter it out with Flowmaster Universal Resonators.
Like an equalizer for your exhaust system, Flowmaster Resonators dial down the bad tones without stifling the good notes. You're left with a quieter cockpit inside and a richer, purer purr outside—all without adding power-robbing restrictions to your exhaust. Plus, they're built from your choice of 409S stainless steel or 16-gauge aluminized steel for years of dependability under harsh conditions.
Universally designed to fit a wide range of vehicles, Flowmaster Muffler Resonators come in a host of sizes and inlet/outlet patterns. Whether you're replacing your stock resonator or adding one to a resonator-less system, you're sure to find a Flowmaster Resonator that fits. What's more, they're backed by a 3-year warranty for aluminized steel and a limited Lifetime Warranty for stainless steel.

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.
