Exhaust note

[hdiam1950]

On the 2019 Gen 3 GTC W12 the exhaust note is fairly quiet. If you drive in sport mode then the exhaust note is much more pronounced but the car is not so smooth to drive and holds the gear changes longer. Does anyone know if there is a way to retain the louder exhaust note but not have to drive in sport mode? Harry.

When I had the W12 I put a Larini exhaust system on it, that seemed to do the trick (well made too)

Harry,

From memory, the exhaust has vacuum operated valves in the rear mufflers (silencers). Try disconnecting the vacuum hoses to move the actuators to open the valves. I can't remember if they are open with or without vacuum, but that is where I would start!

Good luck!
