IC Bus School Bus Exhaust Parts: Fitment Guide for CE Series and RE Series
Updated: Sep 11
IC Bus school bus exhaust parts require chassis series and engine confirmation before ordering. The CE Series and RE Series are different chassis with different exhaust routing, and the MaxxForce engine family has specific EGR components that fail regularly on school bus duty cycles.
Which IC Bus School Bus Exhaust Parts Fit CE Series vs. RE Series?
CE Series and RE Series are two fundamentally different chassis. CE and RE exhaust parts are not interchangeable. Confirm chassis series from the VIN or chassis data plate before ordering any IC Bus school bus exhaust parts.
These are the top-selling IC Bus exhaust parts across CE and RE series. For the complete IC Bus range by engine and part type, browse the parts catalog.

CE Series: Type C, front-engine, conventional hood - the most common IC Bus in school bus fleets
RE Series: flat-nose, forward-control - different chassis layout and different exhaust routing throughout
IC Bus Engine Options and What They Affect
Engine family determines EGR components, exhaust pipe routing, and emissions tier. Confirm from the engine tag before ordering.
MaxxForce 7: V8 diesel - found in CE Series mid-production years - specific exhaust pipe routing
MaxxForce DT: inline 6 - most common IC Bus school bus engine in active fleet service - EGR system failure is the most common maintenance issue
DT 466T: older pre-emissions engine - simpler exhaust system, no EGR - still in service in older fleet units
IC Bus CE Series Exhaust Parts
Exhaust pipe: part NAVCE427 for CE Series - confirm engine and year before ordering
Fuel tank: NAVGT30C91 for IC Bus (call to confirm CE vs. RE fitment)
Fuel tank: NAVGT10C92 for IC Bus (call to confirm fitment by year and series)
EGR cooler: ICEGR261 for MaxxForce DT (2008-2010) - frequent replacement item on school bus duty cycles
Fitment questions framed around engine platform and OE number instead of chassis series are covered in the IC Bus fitment guide by engine and OE number.
What to Confirm Before Ordering IC Bus Exhaust Parts
Chassis series: CE or RE (VIN or chassis data plate)
Engine family: MaxxForce 7, MaxxForce DT, or DT 466T (engine tag)
Model year
Component being replaced - confirm whether it is chassis-specific or engine-specific before ordering

Frequently Asked Questions
What is the difference between IC Bus CE Series and RE Series exhaust fitment?
The CE Series is a Type C front-engine conventional hood chassis. The RE Series is a flat-nose forward-control chassis with a different engine compartment layout. Exhaust routing, muffler position, and pipe configurations are different between the two. Always confirm chassis series before ordering exhaust components.
What engines did IC Bus use in school buses?
IC Bus CE and RE Series ran International engines, primarily the MaxxForce 7, MaxxForce DT, and the older DT 466T. Engine family determines EGR components, exhaust pipe routing, and emissions tier. MaxxForce engines are known for EGR system issues that require regular component replacement.
