thanks guys iv taken a few of your ideas and modified them slightly really like the DB buster idea but i think i can make it more efective by custom making one with a blanked off end so it goes down the inside of the back box and is perforated so that the gasses are fored out threw the sound reducing materil surounding the pipe most of the off the shelf ones seem to still have a through pipe though it is a smaller diamiter, i am awere this is going to kill power but im not bothered for IVA i can loose it afterwards.
also i was talking to me old man about it last night and between us we came up with the idea of double skinning the inside of the engine bay then putting fibreglass insulation like loft insulation in the gap so kindo like outer pannel (aluminium) 25mm of fibeglass wool then the very thin stainless since it has supirior heat disapation qualitys and would not add to much weight i think we have a rool of 0.2mm or 0.1mm ss somewere anyway
also i was thinking carpet underlay on the underside of the bonnet to add some mass and dencity to prevent resonence of the bonnet
your oppiniuns would be great
chears tilly
