Is Front pipe the same as downpipe?

Downpipe/front-pipe are used pretty interchangeably here; traditionally (in the turbo Subaru world) the downpipe is the pipe that goes from the hotside of the turbo and forms the first portion of the exhaust (excluding the pre-turbo elements: turbo manifold and up-pipe).
