wot is the best dump valve for a 2004 wrx sti with ppp please help thanks

 

The standard one it came with.

 

hks ssqv tend to be the favourite these days, not cheap at £250, but they all rave about them.

Depating whether to get one myself, heard they add a few pops from the exhaust

 

Wot 'e said ^^^^

Spend the £250 on a rear ARB, some droplinks and a decent geo set-up, anything left towards some springs or go the whole hog and save up for coilovers. A VTA DV will not give you anything more than a noise, NOTHING
