Hi All, I haven't long had my S3 and can't wait to start giving it a few subtle mods. I've just grabbed myself a Forge 007p Dump Valve as so many of you seem to rate them as being the best replacement, which should be with me tomorrow. After reading lots of previous threads about Cone/Panel Filters etc. it seems that the Green Cotton Panel Filter is also the way to go... but can you get these only from Green Cotton them selves or are they sold elsewhere? Just to confirm though, the part number for the one I'm after is P646531 and is about £50? Cheers, Sean.
