An exhaust pipe structure includes a front bank exhaust pipe connected to an exhaust manifold on a front bank of the V engine; an intermediate exhaust pipe connected to a downstream side of the front bank exhaust pipe; and a rear exhaust pipe connected to a downstream side of the intermediate exhaust pipe, wherein the front bank exhaust pipe and the intermediate exhaust pipe are connected with each other via a ball joint, the intermediate exhaust pipe and the rear exhaust pipe are connected with each other via a ball joint, and a flexible pipe is attached to the front bank exhaust pipe.

The disclosure provides a fixing device for connecting an exhaust system component to a vehicle body, including: a carrier for attachment to the vehicle body; and an elastomer element connected to the carrier. The elastomer element has a connection recess into which a widened end portion of a holding element of the exhaust system component can be inserted, such that a connection region of the elastomer element defining the connection recess at least partially undercuts the widened end portion of the holding element in a joining direction. A fixing device comprises a stiffening structure stiffening the connection region of the elastomer element to impede an extraction of the widened end portion of the holding element.

A vehicle having a frame and an internal combustion engine. An exhaust system extends from the internal combustion engine. The exhaust system includes an exhaust muffler with an exhaust hanger. The exhaust hanger is secured to the frame with an elastic member. An internal heat shield is located on an inner surface of the exhaust muffler to form an interior space between the internal heat shield and the exhaust muffler. The internal heat shield reduces the heat transferred to the elastic member.

An isolator mount for supporting an exhaust component on a vehicle body via a hanger. The isolator mount includes an isolator element, isolator bracket, and clevis bracket. The isolator element has an aperture for receiving a portion of the hanger and dampens vibrations. The isolator bracket extends at least partially about and supports the isolator element and further includes a neck portion. The clevis bracket has a first half and a second half that are secured to the neck portion of the isolator bracket with a fastener that extends along a longitudinal axis. The first half of the clevis bracket and the neck portion of the isolator bracket include an anti-rotation feature in the form of a key-way slot and a key that is received in the key-way slot to prevent rotation of the isolator bracket relative to the clevis bracket about the longitudinal axis of the fastener.

A holding device for retaining an exhaust pipe of an exhaust system with a mounted supporting device includes a carrying portion for accommodating the supporting device, and a fastening portion for fastening the holding device to a vehicle. In an embodiment, the fastening portion has a spring member with a snap-in hook for forming a snap-in connection.

An elastic support for an exhaust system includes a support body, which is made of an elastic material. The support body includes a first fitting opening into which a first bracket is fitted and a second fitting opening into which a second bracket is fitted. An axis of the first fitting opening is orthogonal to an axis of the second fitting opening.

A heat cover device of a catalytic converter for a vehicle may include a shell of the catalytic converter, and a heat cover including a left cover and a right cover that are secured to an external surface of the shell, wherein each of the left cover and the right cover includes a support cover portion which is open outwards and then exert an elastic restoring force inwards after being open outwards, and a close-contact cover portion which is circular-arc shaped to be in contact with the external surface of the shell and integrally extends to both end portions of the support cover portion to be tightly fitted and secured to the external surface of the shell due to the elastic restoring force.

An isolator mount for supporting an exhaust component on a vehicle body via a hanger. The isolator mount includes an isolator element, isolator bracket, and clevis bracket. The isolator element has an aperture for receiving a portion of the hanger and dampens vibrations. The isolator bracket extends at least partially about and supports the isolator element and further includes a neck portion. The clevis bracket has a first half and a second half that are secured to the neck portion of the isolator bracket with a fastener that extends along a longitudinal axis. The first half of the clevis bracket and the neck portion of the isolator bracket include an anti-rotation feature in the form of a key-way slot and a key that is received in the key-way slot to prevent rotation of the isolator bracket relative to the clevis bracket about the longitudinal axis of the fastener.

An exhaust pipe support body including: an attachment member configured to be attached to one of a vehicle body and an exhaust pipe; a center attachment part configured to be attached to another of the vehicle body and the exhaust pipe, the center attachment part having a vertical lengthwise dimension that is larger than a lateral widthwise dimension thereof and being arranged in an installation hole provided to the attachment member; and a plurality of connection arms elastically connecting the center attachment part to the attachment member, the connection arms being integrally formed with the center attachment part and remote from each other in a vertical lengthwise direction between opposed faces of each of left and right sides of the center attachment part and corresponding one of left and right side walls of the installation hole.

A hedge trimmer has at least one cutting blade and an internal combustion engine operatively connected to the at least one cutting blade so as to drive the at least one cutting blade reciprocatingly. The internal combustion engine has an exhaust gas muffler with an outlet for discharging exhaust gases from the exhaust gas muffler. A multi-part exhaust gas pipe is connected seal-tightly to the outlet of the exhaust gas muffler and connects the outlet of the exhaust gas muffler to an outlet opening where the exhaust gases exit from the hedge trimmer. The multi-part exhaust gas pipe has a plurality of pipe sections, including at least a first pipe section and a second pipe section, wherein the second pipe section is embodied separate from the first pipe section. At least one of the plurality of pipe sections is made of plastic material.
