i have been reading through the data on here for 4 months now and i have just purchased a sti 7 02 model,can anyone give me advice on what sort of dump valve i should get,i have been told various stories but i must say i do like that noise and i will get one even though i have still got two years warranty left on the car,and is there a some way i can remove it easily for when it goes back down the garage for a service

ps by the way i have only just got the computer as well

 

Some popular british ones are bailey or forge, but if you want a very audible one then its the HKS or Blitz.

Do a search and your'll find some more info and a link to a site with some wav files.

Cheers
