EXHAUST SYSTEM - 6.7L DIESEL - P/U





The diesel engine exhaust system consists of:

- Exhaust Manifold
- Turbocharger
- Exhaust pipe
- Catalytic Converter
- Diesel Oxidation Catalyst (DOC)/Diesel Particulate Filter (DPF) Assembly (Cab Chassis)
- Diesel Oxidation Catalyst (DOC) (P/U)
- NOx Absorber Catalyst (NAC) (P/U)
- Muffler
- Tailpipe

The exhaust system must be properly aligned to prevent stress, leakage and body contact. The exhaust components should be kept a minimum of 25.4 mm (1.0 in.) away from the body and frame. If the system contacts any body panel, it may amplify objectionable noises from the engine or body.
