In this pic you can see I have finally put the lid on the cutouts, just need to seal it all up and it will be good to go. But there is a lot more to do just yet. Underneath the car there is a 200mm space to put my twin exhaust. With the exhaust end having a 2.5 inch inlet and 2x3 inch outlet, I made a pair of covers I suppose you could call them, made from 4 inch exhaust pipe, and 200mm long so I have plenty of metal to cut away to get the shape I am looking for.
