Exhaust valves

[Magicman]

Has anyone sorted disabling the exhaust valves yet so you can have "race" exhaust noise all the time?

The Evora exhaust was controlled by a vacuum system, unknown about the Emira. I'd imagine it's a similar system but they could have moved to an electronic actuator.

Theoretically both should be controllable via CAN-BUS.

I will disable mine for the opposite reason: so the car stays quiet all the time!

Hi everyone,

So I have found the below related fuse relays in relation to the exhaust valves control. Wonder if any has figured out a way of hacking this to have the valves permanently open without calling up warning lights?

Where is this from?

 

[Pugwash]

It’s in the handbook. P210 or thereabouts.

Not yet.

This will likely require a module to sit on the CAN bus and respond/acknowledge to CAN ids to the valve controller. Going to take some time for someone to reverse engineer that -- and there's not a whole lot of cars delivered yet.

Would anyone be able to point out the location of the exhaust valves please?

Am I seeing this correctly? Only one side of the rear dual exhaust tips are functional?

It looks like that.

Look on the topside of the area circled. Can’t see it from the bottom.

No, you are not seeing it correctly. The exhaust exit is not visible in these photos.

See below, the exits are higher than the inlets:

A view of the silencer assembly out of the car, for clarity:

And here's a reverse view of the inlet side (left) as though looking toward the rear of the car. Exhaust valve is at the bottom left, in the inlet pipe. When closed, diverted flow passes through the smaller pipe on the way into the silencer.

Ignore the arrows printed on the image, those are part of the disassembly instructions.

Thanks! I'll bet if I were looking at it while the car was on a lift, It'd be much more obvious.

Thanks, now that I know where to look, I can just see a bit of the other side up above on that other side.

Spero che qualcuno possa trovare una soluzione. Evora era così semplice...

Translation of above:

I hope someone can find a solution. Evora was so simple...
