There is now a Librands manifold/sport cat system for the Sigma, about £750, to be used with their 4/4 sports rear system, about £300. Plus fitting.
Oh, and a clock will be connected all the time and will run your battery down - may I suggest wearing a watch.
The most useful interior extra I have found is elasticated door pockets.
