An after-market modification designed for certain diesel engines, this assembly typically includes exhaust piping that routes emissions vertically through an opening created in the vehicle’s hood. The components commonly encompass the necessary ductwork, mounting hardware, and a vertical exhaust outlet. The purpose is to re-route exhaust from the traditional location beneath the vehicle to an outlet on the hood.
The appeal of such a system stems from a combination of aesthetic and functional considerations. Proponents cite improved exhaust flow, potentially leading to increased horsepower and torque. Additionally, the modification often produces a more aggressive exhaust note. Historically, similar modifications have been prevalent in high-performance and off-road applications, driven by the desire for both performance enhancement and a distinctive appearance.
