>>>>>The factory systems on the 4000Q and the ur-Q in particular are
excellent
  and little performance if any is to be gained by an exhaust system
  upgrade only, even for the serious performance driver. Only if other
  serious mods and/or race use (tuning and lightening) is intended or if
  trying to save on $$$ would it really be worthwhle to "upgrade" the
  exhaust on these cars, IMFO<<<<<<

And just the same dia pipe with any kind of muffler is not enough....
