Abstract
A vehicle exhaust system is provided. The exhaust system may include a muffler including a casing, an inlet tube extending therethrough, and an outlet pipe partially disposed therein. The exhaust system may also include an orifice tube that may have a tapered body inserted within an end of the outlet pipe that is disposed between a baffle and a wall of the casing. The orifice tube may also include an inlet portion flared from the tapered body configured to attenuate noise of exhaust gas funneling into the outlet pipe.
