Standard DV
For some reason I've only just been able to notice the standard Dump Valve on my 94 WRX 
When I fit my decat downpipe, will you be able to hear the standard DV more or should I get a FORGE DV?
Thanks

HI Nick
The standard dump valves on Subarus are recirculating and are quiet, only the aftermarket VTA ( vent to atmosphere ) ones make the whooshing noise.
There are valid technical reasons for keeping the original, but...it's your car so do what makes you happy
And changing your uppipe/ downpipe will not make the OEM dumpvalve any louder
Do a search on here about dumpvalves and you will see that they are none too popular
