排气管尾段是排气系统中的末尾一部分，也是排气系统三级消音中末尾一级，其结构和中段排气管一致，原厂规格尾段排气管材料同样采用镀锌铁板、铁管制成，内部也是由回压隔板、和消音棉组成。
The tail section of the exhaust pipe is the last part of the exhaust system and the last level of the three-level silencing of the exhaust system. Its structure is consistent with that of the middle exhaust pipe. The tail section exhaust pipe of the original specification is also made of galvanized iron plate and iron pipe, and the interior is also composed of back pressure diaphragm and silencing cotton.
高性能尾段排气管壳体也采用耐用、耐热的不锈钢材料制成，内部由回转式回压隔板使排气顺畅的排出，采用不锈钢消音棉内裹玻璃纤维消音棉，可在减少排气阻力的同时，保持引擎合理的低转速扭力输出，并大大延长消音棉的使用寿命，使排气管保持稳定的排气顺畅度的同时，能长时间保持正常的消音能力。
The shell of the high-performance tail section exhaust pipe is also made of durable and heat-resistant stainless steel. The internal part is made of rotary back pressure diaphragm to make the exhaust discharge smoothly. The stainless steel silencing cotton is wrapped with glass fiber silencing cotton, which can reduce the exhaust resistance, maintain the reasonable low speed torque output of the engine, and greatly prolong the service life of the silencing cotton, The exhaust pipe can maintain normal silencing capacity for a long time while maintaining stable exhaust smoothness.
近年出现的钛合金尾段排气管，不仅耐高温、耐用性能得到大大提高，排气效率也由于排气温度的提高而得到大大提高，而且钛合金尾段排气管重量轻，材料强度大，与同等规格的不锈钢尾段排气管相比，重量可减轻40%、管壁可以薄30%。但是由于钛合金
In recent years, the titanium alloy tail section exhaust pipe has not only greatly improved its high temperature resistance and durability, but also greatly improved its exhaust efficiency due to the increase of exhaust temperature. Moreover, the titanium alloy tail section exhaust pipe has light weight and high material strength. Compared with the stainless steel tail section exhaust pipe of the same specification, the weight can be reduced by 40% and the pipe wall can be thin by 30%. But because of titanium alloy
材料加工难度大，又需要使用激光焊接，故成本比不锈钢产品高近一倍
Material processing is difficult and laser welding is required, so the cost is nearly twice that of stainless steel products
