Hi guys, I've just recently purchased a set of TPO Beast-R velocity stacks from bellissimoto (identical to the corse dynamics ones). I had been eyeing them up for a while and was prompted to buy them as TPO have just shut doors as of February/March this year, which means that the WASP stacks will be the only ones available once the TPO/corse dynamics sell out from their respective sites. Back to the point, I decided to purchase them stand alone (W/O airfilters and brackets) to cut down on postage fees + imports tax and I also prefer foam filters too. Would anyone please be able to tell me the dimensions of the filters included with the kit (or any other velocity stack kit) as I'm going to have a custom pair manufactured by Ramair (unless they have a similar sized one already). I need the following dimensions: Filter height, from filter base to top (excluding the flange length) Filter bottom diameter Filter top diameter Flange diameter (worth mentioning the intake diameter of the stacks is around ~94mm, in case anyone else is using other stacks) I'm led to believe that the Ducshop set came with a pair of K&N RC-9160 air filters, although I'm not sure of the dimensions of the Ducshop stacks so I'm unsure whether they'd be suitable for me (dimension wise). Cheers!
