Why Do Trucks Have a 'Chimney' Instead of a Tailpipe? #Video

Why do some trucks have tall exhaust pipes that look like chimneys, while cars hide their tailpipes underneath? In this video, we uncover the real engineering reasons behind vertical exhaust stacks on heavy-duty trucks. From extreme heat management and engine efficiency to safety on worksites and protection for trailers, every detail of that towering pipe serves a purpose. We’ll also explore how modern emissions technology is changing truck exhaust design and why the classic vertical stack remains an icon of power and practicality. By the end, you’ll never look at a semi-truck the same way again.
