Abstract:
The invention relates to a method for manufacturing an exhaust element of an exhaust line of a vehicle with a heat engine. The exhaust element includes a box having, internally, at least one compartment and at least one tube extending at least partly inside such a compartment. The method includes inserting sound-insulation into at least one such compartment. The insertion is ensured through injection into such a compartment through an opening in the tube from the inside of the tube. The invention also relates to an exhaust element obtained by implementing this method, including forming a box with at least one compartment containing sound-insulation and at least one tube extending at least partly inside at least one such compartment, the tube having an opening provided for in the body of the tube.
