Video showing my '13 Dart 2.0 completely stock, intake only, and intake with Hearthrob Cat back exhaust. In car shots were all with the exhaust installed. Has alower rumble and will crackle and pop if you want it to or be fairly refined when not on the throttle.
Sorry for buzzing and excess noise on the in car shots it was filmed with a phone on the dash. Doesn't buzz that much in reality.
