| To Hs.{Lord Ernest Hives - Chair} from BJ. X 8490 BJ4/H18.3.25. CUT-OUT. Have we ever considered the desirability of having the cut-out at the rear of the exhaust pipe, so that the fumes do not enter a closed car through the floorboards, windows, etc? Or is it considered that this is not an advantage owing to the back draught? B.J. | ||
