So i got a tsudo catback, with stock headers and downpipe, as well as a custom cold air intake. When i am on the road it seems my exhaust sounds quieter between 3500 and 5500 rpm's and then the cold air overtakes at 5500 and i dont really hear much exhaust at all. is this because the limitations of the headers and downpipe? and if i were to put new headers and downpipe on would that make the car sound ricey? and i have an 06 lt 2.2 auto what would u recomend for the headers and downpipe?
