It seems that a stock gasoline exhaust system is quieter than the stock diesel exhaust system on pickup trucks. For example, the exhaust on a Ford pickup truck with the 5.4 Triton gasoline engine doesn’t seem to be as loud as one with the 7.3 Powerstroke diesel engine. I’m not talking about the clatter from the diesel engine, I’m saying the sound from the exhaust pipe itself seems to be louder. If I’m not mistaken, and the exhaust system is louder, what causes it to be that way? Is there more exhaust pressure from the diesel?
