Hello
I am new to the forum and also a new GT350 owner.

Need some help with a couple of exhaust questions.

I need to lock the exhaust valves in silent mode, is there any easy way to do that?
If I remove the cables from the motors at the mufflers, will that work or will the system set a fault code?

Thanks for help.

I dont have an answer to the question but, the valves are closed by default. They only open under WOT if not manually opened via the toggle or mode switch. Are you saying you dont want them coming open ever?

There is a plug/connector type thing floating around out there that will let you apparently disable the valve in either position without a code. So yes, something does exist to accomplish that. Sorry I don't have a link; not something on my radar. No, you cannot just unplug them without a code.

Curious though...the valves are easy enough to stay in quiet mode...just select it and don't go WOT. Why do you need this function?

Hello and thanks for the reply.

Yes, you are right..
I live in Sweden and have just received my car from the US.
Our laws say that the car can only have a sertain DB level.
When I do the test for registration I need the valves to stay closed...
After I passed the test, I can switch back and have the louder sound.

Does the test require you to do wide open throttle? I think unplugging the actuators while close would leave them closed.

I dont know if they will do a wide open throttle..
The test are done in following steps.
They pass a decibel meter 4 times. (2 left side and 2 right side)
2 on 2:nd gear and 2 on 3:rd gear.
During the pass they accelerate.

I have noticed that if you dont hit full throttle, the mufflers dos'nt open up.
But I don't think I can tell them how to drive or how much gas they can give during the test...

Great...
So, if I understand the tread right, I only pull the cables loose (in closed mode) and they will stay there until I put back the cable!
This will also not give me any fault codes..
No, this is not correct. If you unplug them, you will trip a code (unless you have the defeat module that madlag posted). The position of the valve is irrelevant.

Thank you.
Then I have to find out whats the best alternative..

Since I'm in Sweden, its a bit tricky to get the modules but I can easy erase a code.

Its great that you have a GT-350 in Sweden. I know how y'all love the american V8's there. My grandparents were born in Sweden, Varberg and Varmland. Still have extended family all over there.

There are very very few GT350's here in Sweden and I a'm very happy with mine. Need to get it registrated so I can drive on meetings and shows.
By the way, I live 30 miles from Varberg... =)

My grandparents were born in Sweden, too. Near Vaggeryd. Was in Sweden for the first time two years ago and I loved every minute of it. I will be going back this fall. Sure didn't see any GT350s when I was there. I bet you get tons of looks when driving yours. Good luck with your issue and I hope you get it figured out. Adjo och ha en trevlig dag!
