dump valve on a 05 wrx
 

ive recently purchased a 05 wrx impreza and im keen on fitting a dump valve but ive been told various stories about baily dump valvesand forge im not sure what is the best move,also are they easy to fit or best left to a pro :wonder:

As a rule I would not recommend fitting an after market dump valve. The standard one is more than adequate. Only really worth doing if big bhp is involved. Save your money for some performance enhancing mods:norty:

yeh maybe your right

But they sound great and i have never had a problem with any of mine !!!

I'm running 330bhp 03wrx wagon, the baily is a + for me, much quicker and direct to the high speed.Very little knowledge needed to fit

I'm running std bhp on 04 wrx fitted bailey DV and throttle response is much better
