You wont get a chirping noise via a dump valve, the chirping noise comes when the air is forced back through the turbo and sounds through the air filter. However this is mildly quiet compared to when an external wastegate is used.

i think my dump valve pipe is 1" internal dia, so all you need is a bit of tube 1" or 25mm external dia bout 60mm long and get it welded in the pipe between the turbo and the throttle body, and then get a bit of samco or similar 1" internal bout 100mm long to connect the valve to, then the vacum pipe on mine is 'T'ed off the vac pipe that goes to the fuel pressure reg.
hope this helps.

yep weld a outlet on your pipework preferably around 2 inches or so away from where it bolts to the inlet manifolds throttle body. Then the reference pipe that needs to go on top of the dump valve can connect up to a disused blanked outlet that you can find attached to the bulkhead above the hydraulic clutch fluid pot
