I don't know - does the factory twin pipe share the same ED as the Fujitsubo ?
The simple answer to that is 'no', but what's Fujitsubo got to do with it?
Factory twin-pipe system will warm up the RH side of the passenger footwell on RHD cars and the RH side of the driver's footwell on LHD cars. Stock factory single-pipe less so, but still a factor. It's just the nature of the drivetrain.
