Abstract: 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.

Abstract: A single-piece tubular shell for an exhaust device includes a first peripheral wall portion, a second peripheral wall portion, and a third peripheral wall portion. The first peripheral wall portion at least partially defines a first interior region having a first longitudinal axis extending therethrough. The second peripheral wall portion at least partially defines a second interior region having a second longitudinal axis extending therethrough. The second longitudinal axis is non-coaxially aligned with the first longitudinal axis. The third peripheral wall portion extends between and connects the first peripheral wall portion and the second peripheral wall portion such that the first interior region and the second interior region are in fluid communication. The first peripheral wall portion, the second peripheral wall portion, and the third peripheral wall portion are integrally formed and define an uninterrupted, smooth shell inner surface.
