Cheers

hi, ive got one fitted to my94 wrx-sti-1, the purple insert is the quietest insert, but even with that insert fitted, is way louder than any other dlow off, dump valve i ever heard, but these blow off valves are closed mechanically, and allow very quick response, hope that help,s mark

Excellent! Mines arrived and it has a pruple insert. I have to wait on the flange before fitting and was hoping I wasnt going to have to spend more cash getting a louder insert. Sounds like I will be fine running purple
