Abstract: The invention relates to an apparatus for cooling exhaust gases from an internal combustion engine, the apparatus comprising: an exhaust tailpipe (21; 31; 51) having a proximal end (23; 33; 53) and a distal end (24; 34; 54), the proximal end configured to receive exhaust gases from the engine, and the distal end configured to expel the exhaust gases into the atmosphere. The proximal end (23; 33; 53) has a circular cross-section and the distal end (24; 34; 54) has a C-shaped cross-section, where the change in cross- section occurs at a predetermined rate along a predetermined length (L 1 ; L 2 L 3 ) of the tailpipe between the proximal end and the distal end (24; 34; 54).

Abstract: A method for producing a damped part where a sand core is formed with at least one dampening structure with the sand core. The sand core with the at least one dampening structure therein is located in a mold. A part is cast from the mold and the sand core. The sand core is removed from the cast part leaving the at least one dampening structure in contact with the part.
