added to 2015 tacoma dbx exhaust
Got the dbx series exhaust for my tacoma, which sounded great but droned like I ran over a crotch rocket with a pinned throttle. This resonator reduced drone, and quieted the exhaust down just enough to make it enjoyable. I'm all for loud, but with upgraded speakers maxed out loud enough to make my ears ring, I could still hear the drone before the resonator.
No more drone!
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.
