Looking to buy a new dump valve as my current one I've had on since i bought the car only seems to open and close halfway... tried taking apart and cleaning and using a lot of oil but works for abit then gets stuck again.

What kinda brands are people getting and do they all sound different? I was looking at getting a forge one to match my new header tank but even then there is a few options.

I'm running a GFB adjustable (altho running on 100% atmo) and it's really good. High quality, adjustable spring and makes a nice PHHHSSSSSST noise :D
