Does the GTS have an ‘active’ exhaust? By this I mean in standard valves shut mode, do they open above a certain rev range?

From my understanding, 4.7’s all have valves exhausts, 4.7 auto box opens above 3k rpm, MCS closed in normal open in sport.

Does the MCS open above 3k rpm out of sport?

GTS MC-Shift valves are open when engine off, then close after starting, then open in Sport mode at any and all rpm.

The Strads are a bit different.
Open on start up
Closed in Auto
Closed in Sport - opening U.K. at 3000rpm
Open all the time in RACE

Well that’s my understanding anyway

Has anyone got the Larini valve control remote kit on their GTS? If so, is it worth it? I'm thinking about replacing my rear boxes as the valves are knackered.

I'm pretty sure my 4.7 auto also opens the valves at any rpm when in sport AND when the gearbox is in manual... But maybe I'm dreaming?

I think it does but it's whether the 4.7 MCS does the same in manual. I can't test mine until I get her back from the MD, she's getting pampered to the tune of £4k :)
