I like both!

I've got a D/V because I use the standard airbox which doesn't amplify the chatter much.

For me using the piper X induction kit massivly hits economy. With the standard box and ITG I get like 210-230 miles. With the piper X I get 170-200 at the best, with no noticeable power increase.

However I want some sort of noise so DV it is! Chatter does sound better though :)

You don't need a dumpvalve on your RST unles you are running 30psi of boost (unlikely) or using a turbo of T4 size or greater (again not likely).

At least chatter is a byproduct of an induction kit. With a dump valve you have to part with cash to sound like a bus, which is a million times more gay. :P

Not possible I'm afraid if you can hear more audible chatter than before the DV isn't doing it's job. Either that or you're mistaking the sounds

You can usualy run 30psi without a dumpvalve :wink:

Only time i would use a dump valve is on T4 or GT range of turbo.
