Can I just double check what the difference is with having a quad exhaust and the oval type exhaust? Do they both have valves to open and close on sport mode? Assume both 4.7? Example with quad exhausts. Many thanks

It does get a little confusing, but if I remember right....
4.7 early cars -
Oval pipes = MC-shift . Valves open when Sport button is pressed.
Quad pipes =Auto. Valves open only when Sport is pressed and revs are over around 3.5k rpm (unless its an MC Auto then acts as MC_shift above)
Facelift cars (2012/13 onwards) all had oval pipes that open with sport mode.
Correct Sam, to clarify, an ‘MC Auto’ being a 12MY car with optional sport pack; therefore having oval pipes a la MC Shift or 13MY Granturismo Sport.
