A tail pipe for a muffler is provided that can improve aesthetical appearance of a rear surface of a vehicle, while preventing noise that is generated by air currents. The tail pipe may be a hollow tail pipe which is disposed at a rear end of a rear exhaust pipe connected to a rear end of the muffler, and which functions as an outlet adapted to discharge exhaust gas. The tail pipe may include: at least one panel forming an interior surface and an exterior surface opposite to the interior surface; a space surrounded by the panel and formed between the interior surface and the exterior surface; a receiving hole formed at the interior surface; and a barrier mounted in the space and partially protruded through the receiving hole, where the barrier collects soot from the exhaust gas.
