Please be aware that the DMGRS T piece is only suitable if your car has a PRT. My 1.8T has original thermostat at the back of the engine,no PRT and the pipework is very different.
I understand most 1.8Ts have a PRT fitted so yours may be ok?I suppose one of the replacement T piece outlets could be blanked off.
Having said all that, my T piece is original plastic one and still OK at 20 years old....
