I just ordered my Corsa Exhaust from Pro-Motion Tuning in VA. They are going to be installing it Friday. When I talked to Brian over there, he told me the differences between the Corsa and the Zoomers and I definitely think the Corsa is the better option. Corsa and Zoomers are your only options for exhaust with no Drone. SLP is LOUD and so is the Borla....
