You know how the new GM trucks switch from a v8 to a four cylinder, just wondering if you put straight exhaust on one will it sound like V8 or like a rice burner or will it switch with the motor?

itll be louder when its on 8 cylenders than 4, but if ur getting on the gas itll be on 8 so u dnt have to worry about the noise of it when its on 4 cylenders, because if ur cuzin itll be on 4 and quit and switch to 8 on the gas when u want to hear ur ponies

i think the 90s models should be loud but the new ones just dont look like they should be loud
