I have a stock 2012 A4 Quattro and I am completely obsessed with it. I am, however, interested in upgrading it performance wise, as I have done some cosmetic upgrades as well. I have no idea where to start on upgrading it. I want to increase its power, speed, and sound. I'm not asking to upgrade it to S4 status or else I would have gotten one, but just enough to where I can notice a difference in perfomance and power. I know that exhaust is a good way to go as far as performance upgrades but I have no idea how, as there are many parts to an exhaust upgrade. Please just post your input if you would and I will be greatly appreciated. Im not looking to do an engine switch or anything that drastic, but more horses are welcome always, so any help would be great!!!!!!! THANK YOU!

Vive La Audi!
