Ie done a search, I want to get a silicone reducer for my unsilenced ko3s, is it best to just get a straight reducer or a 90degree bend reducer? What heat temp does it have to withstand? Are these any good?http://www.ebay.co.uk/itm/63mm-to-51mm-SILICONE-STRAIGHT-REDUCER-HOSE-BLACK-UK-/300458865227?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item45f4be724b
