Cummins ISX Single Cam Parts – Exhaust Section

A healthy exhaust path protects turbo efficiency, controls heat, and keeps emissions equipment performing as designed on the ISX Single Cam. This section groups the core service items you’ll stage together when addressing exhaust-side maintenance, from EGR heat exchange to clamps, insulation, and hardware.

EGR Cooler (ISX, specific CPL coverage)

What it is: A high-capacity heat exchanger that cools recirculated exhaust gas before it re-enters the intake.
When to replace: Recurrent coolant loss, white steam from the exhaust, oil/coolant cross-contamination, or EGR-related fault codes.
Selection notes: Match to your engine CPL. Always pressure-test the cooling circuit and install with fresh gaskets.

Manifold Insulation Tape (3" and 4" widths)

What it is: High-temperature wrap for exhaust runners and downpipes.
Why it matters: Lowers surface temps in the engine bay, protects adjacent wiring/hoses, and helps retain exhaust energy to support turbo response.
Use: Apply evenly with adequate overlap; recheck after heat cycles.

Exhaust Connections & Hardware

• Exhaust Clamps (ISX/QSX): Secure bellows, elbows, and joints. Replace when you see soot marks, audible leaks, or warped bands.
  
  

• Industrial Flange (4" I.D.) & Gasket: Service the joint between pipes or muffler sections; pair with a new gasket any time the flange is disturbed.
  
  

• Muffler (4" NPT inlet/outlet) & Rain Caps (3", 3.5", 4.5", 5"): Control backpressure and sound while protecting the system from weather intrusion on stationary/industrial setups.
