Hi I am new to this forum this is my first post so hello to all, just bouught my first impreza and was going to buy a dump valve, there are so many on the market I don't know which to go for, I am looking for one thats gives a good noise but no running problems as suffered that before with my focus rs. I have a sti8 with PPP fitted, any infomation would be much appreciated.

 

Hello and welcome. There are loads of opionins on here. do a search, loads of stuff. The main thing is to get a RC valve.

 

So if I get a RC valve this will prevent stalling and give me a whoosh noise

 

the whoosh noise is on vent to atmostphere valves. lots of opinions for and against. just don't get rid of your oe one you might want to re use it after a while
