Freiburger and Mike Finnegan later slapped a tunnel-ram intake onto its low-compression 318 cubic-inch V8 to drag race it at Roadkill Nights, resulting in a hilariously slow performance.

The hosts approach the job with their signature blend of ingenuity and disregard for conventional automotive wisdom. They are not concerned with preserving the car’s original lines or value—their only goal is to make the tires fit so that the Challenger can tackle the harsh desert terrain. The resulting appearance is nothing short of apocalyptic, with the car taking on a menacing, post‑apocalyptic stance that immediately draws comparisons to the vehicles from the Mad Max franchise.
