hi, can anyone tell me if there are any sensors that need to be refitted when changing headers and up-pipe on 2005 pre facelift sg9 forester sti?
there are optional bungs....one in the up-pipe itself and one in the manifold, just below where the up-pipe bolts to manifold.
id like to know if there will be sensors on the car to be refiited here or wether they get blocked off due to the foz not running any sensors?
Reason im asking is because id like to prep before fitting, so any info as regards to wether there are any sensors here or not would be a big help, so I can either block them off or get threads in bosses sorted out for sensors.
regards.

 

The one in the up pipe can be blanked off as that's for a temp sensor which your car won't have and the other one is for the A/F sensor which you will need to swap over from your old headers...hope that helps.
