before i start i kno im probably gonna get some stick for putting this up... i tried running my car with out dump valve cause its a lovely sound from the turbo, but has resulted in killing my reconditioned turbo after 800 miles, so im putting an atmospheric one bk on...just wondered which is the best sounding dump valve to use? its a t3 on an st escos...

 

a ggr group A one bit pricey but sound the balls

 

hks ssqv with triple fin insert. Great sound, short and high pitched.

 

i run an apexi one. adjusted to only release above 8 psi, so it only chatters in town traffic

 

i have a HKS SSQV3 on the rx7 and it sounds good a nice clean sound, very loud tho if your outside the car.

 

Whats the name of that one? I'm trying to find an adjustable one for my rst. Trouble is finding a twin piston style. I did have a bailey dv26 but that would be full volume at anything over 2psi and it got pretty annoying.

same as that. they crop up from time to time from uk sellers. only paid £20 for it brand new

 

i,ve got the spec r one (old ) on a saph and think its the best one i,ve heard from any car . A soft spread tshhh that copes well at any level of driving
