Been reading this thread with interest, my scoob got a dump valve thats very loud would like to remove it and fit a re-circ one, where's the best place to get one and the best type???

 

Best place to get one and best type depends on what state of tune the car is in.

If it's standard-ish, running a topmount intercoler, etc, then you can get one for your model from a scrapper, e-bay etc, and none are better than the standard Subaru one.

After 1999 they were bolted to the intercooler, before that they were on the end of a short pipe connected to the intercooler.

 

I love my HKS III, not annoying, looks good...

 

Hi mate, my cars a newage jdm STI bugeye, apart from a green panel fitter and cat back exhaust its standard, looking at a sports cat down pipe and a remap tho

 

i've got a re-circ, resonator delete pipe, Apexi induction kit, carbon air intake and bonnet risers. Makes a great noise underload and when lifting off, best of both worlds, with no engine damage

 

turbosmart dual port:-

its adjustable so you can decide how much air is recirculated like the standard DV n how much is dumped to atmosphere and is therefore audiable. as quiet or as loud as you want it.

 

i've got a Turbosmart Supersonic on my 2003 WRX -- came fitted when i bought it.

It's ok i guess but mpg seems rubbish even for a scoob (this is my 3rd one - first with a VTA dump valve). Also, i'm not sure about the sound outside the car, but inside you can hear a 'flutter' noise when you lift off quick with some boost on, it's cool in a 'sounds like rally car... wooo!' impress the mates style for few days but i'm not sure it's for me.

Going to get a Forge re-circ one i think, nothing wrong with the noises and that but i think standard is for me!
