I’ve had all 3 versions.

4.2 auto with oval exhausts- also had the blip on downshifts but had a “fart” sound on upshifts

4.7 mc shift - best sound with the crackles and pops

4.7 mc auto? - in between the above 2 - I would have liked more crackles and pops. Wonder if an x pipe would fix that?

I can confirm the 4.7 mc auto (sport pack) with the x-pipe fitted does have crackles and pops! I have this combination. I’m in-awe of the super fast gear change too.

I do agree the 4.7 mc shift with the x pipe sounds better. My friend #Bladerunner has this combination

That’s a strange one as the 4.2 did not come with ovals from the factory. Did someone replace the back boxes?

Copied from a previous thread..

I wouldn’t bother with an MC shift if not in a Stradale, especially not over the later Sport gearbox, its excellent in all conditions, whereas the MC shift is excellent in only one condition.

I also really can’t imagine many people with the sport gearbox aren’t anything other than completely satisfied with the sound as is. It’s superb.

The fart is real lol

I have the grancabrio quad tips valved on my 4.2 A specialist told me there is also a difference in oval vs quad tip valved boxes. Which seemed weird to me. I suppose its more a 4.7 vs. 4.2 engine/gearbox combination that makes the difference in sound. I can't imagine they reworked the inside of the mufflers.

Guess we need a 4.7 grancab vs 4.7 coupe sound comparison to really know :p

For a more related question, would an 2007-2009 auto be able to use the later auto software?
