my truck has the stock 350 with ramhorn manifolds and it has about 2-2.25in pipe i havnt measured it but it goes into 26in glasspacks the sit right under the cab centered in the door and dumpes out right at the back of the cab and at idle its not loud at all but you can hear it and normal driving it sounds good and you can hear the radio or passenger fine and when i whomp on it its louder than the 90s trucks with just mufflers around here nad louder than those damn ricers to but it all comes down to your preference
