Adding exhaust after tune? Exhaust thoughts....

Adding exhaust after tune? Exhaust thoughts....
I have a stage 1+ tune on my 2009 A3 TFSI.
Was tuned with stock exhaust.
If I add aftermarket exhaust will this effect the tune?
Also is it worth putting in a whole exhaust system or leave stock or just put on muffler?
