    摘要： The invention comprises an exhaust system for a motorcycle engine which has an outer imperforate casing having a substantially elliptical cross-section and an inner, coaxial, perforate sleeve also of elliptical cross-section which is of lesser dimensions to provide an annulus within the casing which is packed with a gas permeable material, high temperature resistant material such as fiberglass. The muffler has a single piece inlet end cap and a single piece outlet end cap. Each end cap has an elliptical flange over which is received an end of the outer casing of the muffler. The end caps also have integral mounting flanges to receive and support the inner perforate sleeve. Preferably the muffler is provided with a replaceable sound choke which is a small diameter sleeve that can be removably secured in the discharge end of the muffler, thereby permitting the muffler to be switched between restricted off-road use and unrestricted off-road use.

    摘要翻译： 本发明包括一种用于摩托车发动机的排气系统，其具有具有基本上椭圆形横截面的外无孔套管以及也具有椭圆形横截面的内部，同轴的穿孔套管，其具有较小的尺寸以在壳体内提供环形空间 包装有透气材料，耐高温材料如玻璃纤维。 消声器具有单件入口端盖和单件出口端盖。 每个端盖具有椭圆形凸缘，在该凸缘上接收消音器的外壳的一端。 端盖还具有一体的安装法兰，用于接收和支撑内部穿孔套筒。 优选地，消音器设置有可更换的声音扼流圈，其是可拆卸地固定在消音器的排出端的小直径套筒，从而允许消音器在限制越野使用和不受限制的越野使用之间切换。
