I've been away and I come back to read threads like this. I've decided not to mince my words any longer....
I don't think I've ever heard of or seen any idea so dopey as removing one muffler in a twin system and leaving the other one in place, except what I see in the later photos of inserted spacers in the tailpipe pipe flanges which is about as nutty as I've come across in a long while.
Apart from being dangerous from a fire issue, there is also potential for carbon monoxide ingress into the cabin space; it is mechanical vandalism of the 1st order that no car, far less a fine one such as the MPS6, should ever be subjected to. Such modifications lower the entire "tone of the neighborhood" of genuine enthusiasts who truly care for their cars, and should be strenuously discouraged. It's a shame that these cars are now becoming so cheap that some folks with more money than sense can get their hands on them and do this sort of thing to them.
And in my view, lots of noise usually just says "look at me - I have no idea what I'm doing and it's no doubt stuffing my car up and lowering the resale value but doesn't it sound great".
There seems little point in adding noise if it isn't associated with some genuine power benefit.
