Is it safe to drive with a missing muffler?
Driving without a muffler risks exposing the vehicle's underside to excessive heat and potentially leaking toxic exhaust fumes into the cabin if components near sensors are open. This leaves drivers unsure whether they can safely make short trips to work or run errands before affording a replacement.
