Mk5 Golfs have a divrter valve and not a dump valve. Best one is the OEM Revision G, £35 from your local dealer.  :happy2:

Forge do two different spacers if it's noise your after ? One fixed, Full blow off and the other, an adjustable one which has 3 settings, fully blow off which is loud, partial blow off/ partial re-circulate, slightly quieter and then full recirculate which is quiet and will help the car keep stronger boost. These are bolted onto the diverter valve. I personally don't have a dump valve just a revision D diverter valve which I will prob swap for a G soon. A nice induction kit and a standard diverter D or G revision combo will sound and perform better than adding a spacer just for noise. Each to their own I suppose

The forge spacer sounds terrible and actually LOSES power as it leaks.

If you want loud blow-off noises you should consider a scooby  :happy2:
