Flowmaster Outlaws, 2011 GT 5.0

Fit and appearance are great. Easy to install, I had a muffler shop do the work.....! Car sounds like a muscle car should. I have 3.73 gears with the 6 speed, and at highway speed with the windows up, you just hear a nice purr. But, at 2000rpm there is a real drone, especially with the windows rolled up. Any suggestion on how to cure this problem? Thanks for your quick service getting the mufflers shipped in record time. Regards.

I spent several hours looking at video clips online trying to decide on what exhaust to get. I had finally decided on the Flowmaster outlaws, and couldn't be happier. It has a very deep tone to it, along with some drone 2,000 rpm, but nothing that's unbearable. I would strongly recommend this axel back to anyone that wants to be heard.

The hardest part of the installation was removing the stock mufflers, after that everything else was simple (30 min). It has a very loud sound and some drone but it's expected.
