It's certainly the case with mk5 Golfs and SEAT Leon mk2s too, the exhaust parts are directly interchangeable between the TFSI/TSI and TDI models.
I looked into getting a GTI back box on my mk5 Golf GT TDI before the 170s came along with the twin pipes. It would have been a direct fit and is a conversion many people have done since.
