Your car came with a single exhaust
You can get the Y-Pipe and that will allow you to use two mufflers.
You will need to cut a notch in your valance for the added pipe.
You can also get everything you need to get to do the duels correctly from American Muscle or other Vender's.
If you decide to go to a muffler shop you need to be aware of their reputation for doing custom applications. Some of these shops are "Butcher Shops" and will do it but not do it right. Go to your local speed shop to find out who does the best custom exhaust in your area.
I'm sure there are some 2010 owners on the Forum that can help you out.
I don't think you are wrong to ask for the information you want on this forum. If someone don't want to read about another exhaust question they really do not need to open the post.
