Hi, Basically I purchased my 225 a few months ago and was over the moon with having my first turbo car that hasn't blown up within a fortnight (200sx S13 x 2) and the previous owner had fitted a Forge BOV which is quite atmospheric and unfortunately I can't find the invoice for it but I'm assuming it's not a recirc valve. I got my backbox chopped on Wednesday and I can't really hear it over the BOV so I was wondering if anyone knew how to quieten them down and if the standard parts (which I still have) still give off a little whistle on gear changes as I'm starting to realise the BOV is a little chavvy if I'm honest. Also if anyone knows of a guide to remove and swap, that would be helpful. I should note that I have a KTR Blanking plate fitted as well so not sure if this makes them louder? Cheers
