Wondering what exhaust system would be the best for power, that has a deep rumble and is loud. Im a noob here, so im not really sure. I was leaning towards a borla system b/c i hear they are deep. I will not buy anything but the best! And I would like the car to be legal....but if it makes a big difference...I will do otherwise if its worth it. Oh and I want to put true duals on there too. Im not sure what thickness the pipes or muffler tips should be. What do you guys think?
