Just curious if anyone had any wastegate alternatives for the APS ST unit. I don't want anything too obnoxious but a nice pssht whistle between shifts would be fun.

I think you are talking about the blow off valve. A couple guys have switched out theirs already. Maybe Greddy Type-S.

 

Isn't Wastegate another word for Blow Off Valve? Anyhoo thanks for the input

 

Na, its 2 different things. A turbo has 2 sides, the Turbine side for the exhaust, and the Compressor side for the Intake. The blow off valve is on the intake pipe and its job is to relief the compressed air between the engine and turbo so as to not to damage the blades on the compressor from all the back pressure created when you let off the gas pedal. The wastegate is on the exhaust and it opens and closes to keep just enough exhaust gases going through the turbine side of the turbo so the compressor side makes the correct amount of boost.
