Copy to - ~~BJ.~~ ~~EV.{Ivan Evernden - coachwork}~~ HS.{Lord Ernest Hives - Chair} PHANTOM EXHAUST SYSTEM. 48230 We have to improve the efficiency of the exhaust system. The only way I know is to increase the capacity or cooling. An aluminium smaller silencer is to be tried - WW. to make a drawing: it is very good, at present, but we lose too much power.
