I want my exhaust valve to be open without sports mode. Anyone tried to disconnect the valve to leave it open permanently? It's a 2011 granturismo 4.7 automatic.

We have a Remote Control Valve Controller that defaults in the loud mode and you can use the button on the remote to quiet it down when desired. Great for owners that want to take the control of the exhaust valves off the Maserati system and have full control themselves. Then you can cruise in Normal mode with a Loud Exhaust for instance which is something you can't do with the factory control and if you like it loud, it defaults in the loud mode so you don't have to switch it every time you startup!

The vacuum line with the 'golf tee' inserted...was removed from the valve, (circled).
Do both sides.
Favors left side a bit. If you just lay on your back and reach UP where the trunk ends, its between that wall of the trunk and the exhaust pipes. Jack up the left rear the first time so you can look at it directly. Once you've done it the first time, its an easy reach the next time. Tim wins the quik draw award again!!!

I have a custom Gintani exhaust on my MC and I always assumed the vacuum lines were disconnected since normal or sport mode made no difference in the exhaust level. Yesterday I finally bothered to look near the mufflers and was surprised that the vacuum lines were indeed connected to the valves. So I took them off and plugged them with a golf tee. And wouldn't you know it, the exhaust went quiet. So looks like the OEM valves are normally open and stay open when disconnecting the vacuum line. I'm thinking Gintani used a normally closed valve in their setup and keep it open using the vacuum line? I imagine they must've had to bypass the solenoid or something so that the vacuum is always active to the valve. Anyways, thought I'd share.
