The Weston Pipes from JDE all have the pressure tap installed on them from the factory.
And a Reminder to all who have purchased the pipe make sure the pressure line from the pipe to the tank is as short as possible this goes for both the tractor and pusher version if the line is left as it may have been with another tunned pipe system it is to long and the air passing over the line will cause it to whip thus causing the line to work on the pressure fitting causing it to pull out of the pipe.
Also the 2 springs that hold the pipe in place should be trimmed so that these springs do not eat into the rubber bumper o'ring or the Cylinder head from vibration.
