Which orientation is described as advantageous because it is not damaged by low bridges or tree branches?

• A. Horizontal exhaust system
• B. Vertical exhaust system
• C. Both
• D. Neither

Answer: (A)

Exhaust orientation affects how exposed the pipe is to overhead obstacles. A horizontal exhaust system sits lower and away from the vehicle’s upper edges, so it’s less likely to be snagged or crushed by low bridges or overhanging branches as you pass beneath them. A vertical exhaust, by extending upward, is more prone to contact with such overhead hazards, increasing the chance of damage. So the horizontal orientation is considered advantageous for resisting damage from low bridges and tree branches.
