Here's What The Shelby GT350R Mustang's Exhaust Sounds Like With No Safety

We've been seeing a lot more of the Shelby GT350R Mustang recently, and that's a good thing. One awesome feature of the beefed-up Mustang is the fact that you can manipulate how loud the exhaust is. Up until now we've only been able to read about the feature, but this video shows it in action. While it may sound gimmicky there's a major difference when you flip the switch and allow the GT350R to roar at full blast. Seriously, unchained this thing will wake up the entire block.

Check out the video yourself to see just how big the difference is.
