This is what I came to post. CF driveshaft is where you're going to get insane bang for your buck. From everything I've seen, past the header replacement you're wasting money buying an exhaust even with a tune.
Keep in mind, people love to throw stupid large heavy wheels on their cars and it's no different. If you can get lighter wheels, tires, driveshaft, flywheel, and crank pulley you're looking at seriously increasing WHP without touching the exhaust.
