An exhaust system comprises a first exhaust pipe having a first aperture, a second exhaust pipe having a second aperture and a bridge mechanically and fluidically interconnecting the first and second exhaust pipes. The bridge includes a first plate including a first curved portion sealingly fixed to an outer surface of the first exhaust pipe. The bridge includes a second plate including a second curved portion sealingly fixed to an outer surface of the second exhaust. The first and second plates each include first and second coupling tubes including first and second frustoconical portions to funnel exhaust from the first exhaust pipe toward the second exhaust pipe and vice versa. The first plate is sealingly coupled to the second plate.

Exhaust pipe bridge

An exhaust treatment device includes first and second substrates positioned in parallel within a housing. A baffle plate supports the substrates, an inlet tube and an outlet pipe, and defines a portion of a first chamber. First ends of the substrates and a second end of the inlet tube is in fluid communication with the first chamber. A partition supports the substrates, the inlet tube and the outlet pipe and defines a portion of a second chamber separate from first chamber. Second ends of the substrates and a second open end of the outlet pipe is in fluid communication with the second chamber. All of the exhaust flows in a first direction through the inlet tube, reverses direction through the substrates and reverses direction again to flow through the outlet pipe.

Tri-flow exhaust treatment device with reductant mixing tube

An exhaust treatment device includes an inlet tube having an end in communication with a cavity within a housing. An exhaust treatment component for treating engine exhaust is positioned within the housing. A metal mounting member includes a mounting provision. A retaining plate is engaged with the metal mounting member and fixed to the housing to retain the mounting member between the housing and the retaining plate.

Exhaust treatment device with integral mount

An exhaust treatment device includes an inner shell spaced apart from an outer shell by a first gap. An inlet assembly includes a first inner cap and a first outer cap spaced apart by a second gap. An outlet assembly includes a second inner cap and a second outer cap spaced apart from each other by a third gap. A substrate is located within the inner shell. An insulating mat is positioned between the substrate and the inner shell and includes a reduced diameter portion compressing the insulating mat between the inner shall and the substrate. Insulation material fills the first, second and third gaps that are in communication with each other.

An exhaust treatment device includes an insulation material positioned between an inner shell and an outer shell. An inlet tube has an end in communication with a cavity defined by the inner shell. A substrate for treating engine exhaust is positioned within the inner shell. A metal mounting ring is positioned between the inner and outer shells and includes a mounting provision for receipt of a fastener.
