That’s the fella! Thanks so much for the picture that looks like exactly what I have in my boot

I can take off my crocodile clips and use the bolts which will be much better. Thanks taking the time to send the pic

On the V8s you can exercise the valves by hand occasionally to keep them mobile if you want.

I have a V8 P575 R and it has the exhaust switch on the console, this seems to open the valves and allows all four exhausts to operate, same seems to apply if I switch it to dynamic mode. Is this the same thing i.e. I don’t need to take out the fuse?

Depending on the MY the exhaust switch operates differently. With the fuse in, the car's electronics control the opening of the valves, which may, or may not, open fully. Removing F15 will leave them wide open all the time. The noise may appeal, or you might find it a bit overwhelming - give it a try and see what you think.

Thanks! I’ll give it a go, I already thought I’d bought a fire breathing dragon! Will be interesting to see what difference it makes

Au contraire - possibly the sanest thing you've done!
