Exhaust Components for Cummins ISM Engines

The exhaust system of the Cummins ISM is essential to overall engine efficiency, emissions control, and reliability. A properly functioning exhaust assembly not only ensures compliance with emissions standards but also contributes to optimal turbocharger performance, engine longevity, and fuel efficiency. Diesel Pro Power supplies premium-quality replacement exhaust components for Cummins ISM engines, trusted by over 40,000 satisfied customers worldwide.

Role of the Exhaust System in Cummins ISM Engines

The Cummins ISM, widely used in heavy-duty industrial and commercial applications, relies on a precisely engineered exhaust system to:

• Manage Exhaust Flow – Safely channel high-temperature gases away from the combustion chamber.

• Support Turbocharging – Provide stable exhaust pressure for the turbocharger to deliver reliable boost.

• Reduce Emissions – Work in tandem with EGR and aftertreatment components for EPA compliance.

• Minimize Backpressure – Prevent excessive strain on the engine and maximize power output.

Turbochargers for Cummins ISM

The turbocharger is the centerpiece of the ISM exhaust system, converting exhaust gas energy into increased intake air pressure.

• High-Performance Turbo Assemblies – Designed to handle the ISM’s displacement and horsepower demands, ensuring consistent power delivery.

• Turbo Actuators – Control boost pressure, preventing over-boost conditions and protecting engine integrity.

• Gaskets and Mounting Hardware – Maintain proper sealing between the turbo and exhaust manifold.

A failing turbocharger often results in reduced acceleration, excessive smoke, or abnormal oil consumption. Diesel Pro Power provides replacement units built to OEM specifications to restore full performance.

Exhaust Manifolds for Cummins ISM

The exhaust manifold collects gases from each cylinder and directs them toward the turbocharger. For the ISM, durability is critical due to sustained high operating pressures.

• Cast Iron Manifolds – Resistant to cracking under thermal stress.

• One-Piece and Sectional Designs – Available depending on ISM configuration.

• Heat-Resistant Gaskets – Provide long-lasting seals between the cylinder head and manifold.

Manifold failures can cause exhaust leaks, increased fuel consumption, and turbocharger inefficiency. Upgrading with a heavy-duty replacement manifold ensures proper exhaust flow.

Exhaust Gaskets and Seals for Cummins ISM

Every connection point in the ISM exhaust system requires precision sealing to prevent leaks and maintain pressure balance.

• Turbocharger Mounting Gaskets

• Manifold-to-Head Gaskets

• EGR System Seals

• Exhaust Flange Gaskets

Using high-quality gaskets is essential to maintaining exhaust velocity and avoiding performance losses. Diesel Pro Power’s gasket solutions are engineered for high-heat resistance and durability.

EGR (Exhaust Gas Recirculation) Components for ISM Engines

Many Cummins ISM engines are equipped with EGR systems to reduce NOx emissions.

• EGR Valves – Control the flow of exhaust gases reintroduced into the intake system.

• EGR Coolers – Lower the temperature of recirculated gases to prevent detonation and reduce combustion temperatures.

• EGR Tubes and Sensors – Ensure precise monitoring and efficient emissions management.

Proper EGR system operation is crucial for EPA compliance and maintaining fuel economy.

Mufflers and Exhaust Outlets

Noise reduction and safe exhaust gas release are important for operator comfort and environmental compliance.

• Heavy-Duty Mufflers – Designed to withstand vibration and heat.

• Exhaust Pipes & Elbows – Direct gases out of the engine compartment.

• Mounting Clamps & Supports – Ensure stability of the exhaust assembly.

Heat Shields and Insulation

The Cummins ISM exhaust system generates extremely high operating temperatures, making heat management critical.

• Exhaust Heat Shields – Protect nearby components from radiant heat.

• Turbo Blankets and Wraps – Maintain turbo efficiency while protecting hoses and wiring.

• Insulated Manifold Covers – Help reduce under-hood heat buildup.

Oxygen and Temperature Sensors

Modern ISM configurations rely on sensors within the exhaust system for performance monitoring and emissions control.

• Oxygen Sensors – Monitor combustion efficiency.

• Exhaust Temperature Sensors – Prevent overheating and protect turbo and aftertreatment devices.

• Backpressure Sensors – Detect restrictions in the exhaust path.

These sensors play a vital role in diagnostics and overall system health.
