For an STI 7:
You don't need one, but you will have to fit a different restrictor to dumb down the boost peaks IMHO, although some are selling them without and these cars are then detting obviously unknown to the exhaust installers.
For the P1:
Less likely to boost spike as wildly or boost creep, but the ECU can hit a lean spot and run into some detonation problems. If you have a knocklink and it is quiet then fine.
