Mike & Paul,
From what I saw somewhere, the 'F' Type exhaust was engineered for the V6 and V8 to give a one off signature for the model. Marketing has decided this type of flavour has had its day, according to research, at least, & Jaguar have gone heavily off it. Exhaust noise in other manufacturer's cars is now done by a sound emission from the car's stereo triggered from information from the car's ecu (as with Porsche & Audi I believe) .As far as noises derived from the exhaust go, this sound is energy that can easier be channelled into making the car accelerate quicker ! In my experience, controlling the gears with the paddle shift derives more benefit from the exhaust note, whereby an intentional gearshift over a ridge in the road, or direction change towards an exit if a roundabout, (or a moment later), aids the 'pointing' of the nose of the car, with the surge in torque at mid-revs settling the handling. Once straightened, my fingers pull on the right paddle for two seconds back to 'D' . In old money, 4th gear in an 8 speed ZF was very close to 3rd gear in the 6 speed ZF, and when the 8 speed gearboxes came in, for instance, the TDV6 diesel had had a few sharp climbs in torque output that corresponded very well . By the same token, tiny roundabouts I take in 3rd , medium in 4th, and greyhound track-like roundabouts, traffic permitting, 5th gear, all three gears being spaced closely around the old 3rd gear in 6 speed boxes. I find this way I achieve great exhaust purr on acceleration.
