* Excessive Noise: The lack of a muffler results in significantly louder exhaust noise, violating noise ordinances. This can lead to fines and even vehicle impoundment.
* Environmental Regulations: Mufflers are part of the vehicle's emissions system. Operating without one can result in exceeding emission standards, leading to further penalties.
* Damage to Engine: While less direct, the lack of backpressure from a muffler can potentially affect engine performance and longevity over time.
In short, while it might be possible to drive a short distance, it's highly inadvisable and illegal to regularly operate a vehicle without a muffler. Replace the muffler as soon as possible.
