Old rusty and newer stainless exhaust pipes on concrete floor

Two exhaust pipe assemblies laid on a cracked concrete floor: an older tarnished/rusty dual-inlet Y-pipe on the left and a cleaner stainless-look mid-pipe with a bulged section marked '3' on the right. A hose clamp and a blue disposable lighter sit in the upper right corner.
