I'm spreading the word.
My Magnaflow cat-backs had the 2000 rpm drone and was driving me crazy. I read some info over in the Corral forums and decided to try it. IT WORKS!!!
The problem is the engines strongest tone at 2000 rpm causes the tail pipes to resonate (vibrate like a pipe organ). The fix is to install Side Branch Resonators on the tail pipes to cancel the tone.
Here's the link to the Corral forum, it's explained in good detail there with pics.
