Although the factory mufflers on the 5.0 Mustang supplied a fair amount of sound, they did not reflect the true power this engine generates. The Force II system is not overly loud,yet, it creates enough rumble to fit the image this vehicle attracts. I would say the sound level increased by 30%. Most of the rumble generated by this system is exterior,slightly louder than stock inside the car with no noticeable drone. For those who want that loud classic 5.0 sound, this system may be too subdued.If you want that V-8 rumble without excessive attention the Force II system works well. More noticeable than stock, but enough exhaust note to make driving the 5.0 more of an experience.
