Forge FMCL007P is the best valve to buy, nice low noise and really easy to fit. Costs around £80 - £90 and a choice of silver or black. GO FOR IT!!!
TIP: always search the forum before asking questions!
Running standard boost and the OEM DV, mine is pretty loud with an open cone induction kit. Is the 007 quieter than the OEM Bosch DV?
or if you are after the sound go with the Turbosmart kompact dual port, equivelant to the split R.
but with out all the hassle of the spilt r
Rob Don uses it and swears by it and he has tried them all so should know haha
