At Diesel Pro Power, we provide a complete catalog of Cummins 6CT exhaust parts built for reliability, durability, and seamless fitment. With over 40,000+ satisfied customers worldwide, we are the leading source for marine and industrial Cummins replacement components.

Below you’ll find a detailed breakdown of exhaust system components for the Cummins 6CT engine. Each description highlights its role, benefits, and why it’s essential for long-term engine health.

Marine Exhaust Manifold for Cummins 6CT

The Cummins 6CT marine exhaust manifold is a water-cooled manifold engineered to handle the intense heat and pressure produced during combustion. It collects gases from the engine’s cylinders and channels them efficiently into the turbocharger or exhaust outlet.

Benefits:

• Marine-grade, water-cooled construction prevents overheating.

• Designed to withstand prolonged high-load operation common in vessels and heavy-duty equipment.

• Manufactured to Cummins OEM specifications for durability and reliability.

This part is a must-have for vessel operators who need a manifold capable of resisting both high thermal stress and corrosive marine environments.

Exhaust Manifold Gasket for Cummins 6CT

The Cummins 6CT exhaust manifold gasket ensures a proper seal between the manifold and the cylinder head. A tight seal is critical to prevent leaks that can reduce engine efficiency and increase exhaust temperature.

Benefits:

• Heat-resistant sealing material designed for the high temperatures of diesel exhaust.

• Prevents exhaust gas leaks that can damage nearby components.

• Recommended to replace all gaskets whenever the manifold is serviced or replaced.

Each 6CT engine requires six gaskets, one for each cylinder.

Turbo Mounting Gasket for Cummins 6CT

The turbo mounting gasket on the Cummins 6CT is used for water-cooled turbochargers, forming a reliable seal between the turbocharger and the exhaust manifold.

Benefits:

• Prevents exhaust gas leakage at the turbo flange.

• Ensures proper turbocharger pressure and performance.

• Built for high-temperature operation under marine load conditions.

Replacing this gasket is essential whenever the turbo is removed to ensure long-lasting sealing integrity.

Exhaust Manifold Bolts for Cummins 6CT

The Cummins 6CT exhaust manifold bolt is a heavy-duty fastener designed to secure the manifold tightly to the engine head.

Benefits:

• Heat-treated steel construction resists warping under extreme exhaust heat.

• Maintains manifold-to-head alignment and prevents leaks.

• Also used in select accessory mounts such as alternator brackets and compressors.

These bolts should always be torqued to the correct specification and replaced if signs of fatigue are present.

Exhaust Outlet Connection Gasket for Cummins 6CT

The Cummins 6CT exhaust outlet gasket seals the joint where the exhaust manifold connects to the outlet, ensuring a gas-tight fit.

Benefits:

• Prevents harmful gases from escaping into the engine bay.

• Maintains exhaust system backpressure for proper turbo operation.

• Built from durable, heat-resistant materials to handle continuous marine use.

This gasket is an inexpensive but critical component in preventing leaks and ensuring safe operation.

Intake Manifold Cover Gasket for Cummins 6CT

While part of the intake system, the Cummins 6CT intake manifold cover gasket plays an important role in sealing air passages. Since the intake and exhaust manifolds are located close together, ensuring a proper seal here is crucial for balanced combustion and turbocharger efficiency.

Intake Connection Gasket for Cummins 6CT

The Cummins 6CT intake connection gasket ensures a tight seal at the intake connection points. A proper seal prevents unmetered air from entering the engine, maintaining smooth combustion and protecting the exhaust system from imbalances.

Exhaust Insulation Tape

High-performance diesel engines like the Cummins 6CT generate extreme exhaust temperatures. Exhaust manifold insulation tape is used to wrap manifolds, pipes, or other exhaust components to retain heat and protect surrounding parts.

Benefits:

• Reduces radiant heat in the engine compartment.

• Protects hoses, wires, and nearby equipment from heat damage.

• Improves exhaust gas velocity, which can aid in turbocharger response.

Available in different widths for various applications.

Exhaust Flanges, Gaskets, and Mufflers for Cummins 6CT

For industrial setups where the Cummins 6CT is used in stationary or auxiliary equipment, flanges, flange gaskets, mufflers, and end caps are available to support customized exhaust layouts.

• Flanges: Provide secure exhaust pipe connections.

• Flange Gaskets: Ensure tight, leak-free joints.

• Mufflers: Reduce exhaust noise in industrial environments.

• Muffler Caps: Protect against debris and backflow when the engine is idle.
