Yea it's mine. If you read all the thread mate it tells you exactly what to do and what parts you need

It's a bit different on the Signum as the back boxes aren't separate like they are on the Vectra. On the Signum it's one huge part. This thread shows the procedure for a Signum.

That's not my thread, but those two boxes in the pic are one part - that's what I was meaning.

Suppose it's possible in theory. It'll be a good bit noisier though as you'll be cutting out a large silencer. Not sure if it might affect the response/feel of the engine.
