The invention relates to an automobile
exhaust pipe. The automobile
exhaust pipe comprises a connecting piece. The connecting piece is internally provided with a fixing ring. The lower part of the connecting piece is connected with a front
exhaust pipe body. The
tail of the front exhaust
pipe body is provided with a three-way catalyst. A middle exhaust
pipe body is arranged behind the three-way catalyst. The inner wall of the front exhaust
pipe body and the inner wall of the middle exhaust pipe body are each sequentially provided with a thermal-protective
coating and a
noise reduction coatingfrom interior to exterior. The
tail of the middle exhaust pipe body is provided with a particle collecting device. A rear exhaust pipe body is arranged behind the particle collecting device. The innerwall of the rear exhaust pipe body is provided with a
noise reduction
coating. The middle of the rear exhaust pipe body is provided with a silencer. The
tail of the rear exhaust pipe body is providedwith an exhaust port. The inner side of the exhaust port is provided with a filter net. A
shock absorber is arranged below the three-way catalyst, and a
shock absorber is arranged above the particlecollecting device. The shock absorbers are connected with extension pipes, and the extension pipes are attached to the surface of the middle exhaust pipe body, the surface of the particle collecting device, the surface of the rear exhaust pipe body and the surface of the silencer. The automobile exhaust pipe has the advantages of being good in cleaning effect, capable of carrying out damping and absorbing
noise and long in service life.
