get a diverter valve rather than a dump valve.
Ie it recirculates the air and doesnt dump it to atmosphere.
trust me. (it may appear to work ok but you dont want a atmospheric dump valve).
if you want more noise look at an induction kit.
welcome to the site, use the search facility and you will be fine.
you wont get abuse that often

(unless you ask about Dump valves)
the bailey recirculation DV is used my many on here, and will be ok, however i would personally recommend the forge 007p. lifetime warranty. they are about £90 or keep an eye on the for sale section.
forge have fantastic customer service.
