dump valve
i have a standard 04 WRX but want to start upgrading. what type of dump valve should i get? i am about to buy a de-cat pipe and louder back box although nothing too loud. any replies welcome.

Personally I would not put a dump valve on a Scoob. Stick with the recirc valve and it will save you problems in the long run. As for exhaust I have a Magnex system, its deep but not too loud. Try and listen to a few as they vary a great deal in db levels.

This is from experience of issues involving dump valves. It is regarded by many, including mappers on here, that the standard recirc valve is by far the most reliable and best item to use. There is no performance to be gained by dumping to atmosphere. Fitting a good panel filter as suggested will give you a whoosh sound while changing gear and not be annoying. Dump valves suit certain cars and IMO Subaru's aren't one of them. I am sure others will agree.
