• Remote Terrain Operations: Curved pipe outlet supports performance in high-dust, steep-angle, or forested work environments.

Installation Tips

• Turn off engine and allow system to cool before removal or installation.

• Clean all pipe junctions before fitment; inspect for soot buildup or residue.

• Use factory-recommended torque values when securing with bolts.

• Always replace gaskets or sealants during reinstallation.

• Test fit exhaust alignment before full tightening to avoid mechanical strain or vibration issues.

• Let the machine idle after installation to inspect for leaks or unusual sounds.
