I know on most cars, if you cut the Cat, you can expect a slight performance gain. It is pretty common practice up here, as we do not have emissions testings. I have been considering having this done as I suspect it is towards the end of it's life.
Will the Volvo start throwing codes and messing up if the cat gets gutted? If so, is there anyway around it?
