Section 2
Safety & Compliance
Noise and Emissions Requirements
NOTE:
NOTE:
This truck may be equipped with a converter muffler unit in order to meet both noise and exhaust
emissions requirements. Removal or tampering with the converter muffler will not improve engine per-
formance. Also tampering is against the rules that are established by the U.S. Code of Federal Regu-
lations and Environment Canada Regulations. The converter muffler may only be replaced with an
approved part.
Relocation of converter muffler will affect noise and emission performance. Contact the engine manu-
facturer for any requirements and restrictions prior to any modifications. In particular, there are re-
quirements and restrictions for exhaust pipe materials and for maximum exhaust system lengths from
turbo outlet to muffler inlet.
