What makes a Cummins Engine so good is that it was designed to be a durable and extremely powerful engine for industrial use. However, all that power comes from a diesel engine that runs at a much higher pressure than gasoline. The main drawback of a Cummins Engine is that it is going make a much louder noise as exhaust gasses try to escape.
You’ll be pleased to know that there are inexpensive automotive sound deadening products available at B-Quiet to quiet down the road, tire and exhaust noise of your Cummins pickup truck.
Why Are Cummins Engines So Loud?
Cummins engines produce more power and torque than standard gasoline engines, and that strength comes with higher combustion pressure and mechanical vibration. Here’s what makes them noisier than most:
- High Compression Ratios: Diesel engines operate at much higher pressures, which means louder combustion.
- Metal Engine Components: Thicker blocks and heavy components transmit vibration directly to the cab.
- Lack of Factory Insulation: Many diesel trucks, especially work vehicles, have minimal soundproofing.
- Exhaust and Turbo Whistle: Turbos, downpipes, and straight-pipe exhaust setups amplify the noise even further.
- Vibration Through the Firewall and Floor: Without damping material, sound travels easily into the cabin.
That’s why even new Cummins powered trucks can sound harsh, especially at idle or under load.
