The SRT has a nice deep authortive rumble. Not some weedwacker sound that most of the 4bangers with coffee can exhaust sound like. At normal crusing speeds and around town, it's pretty quiet inside. You won't have to screem to talk to the person next to you, and you won't have to crank the radio into bleeding. When you get into the throttle, the noise picks up with a nice, deep growl. The car is never abusive to the ears. When it is loud, it sounds perfect. From the outside (behind), the car sounds loud. People on the street will wonder WTF drove past them.
