I have this exhaust. Its a little loud without a cat. And so you know it doesn't come with the section to replace the cat. I thought it was the full turbo-back exhaust. It technically is, but they get you with the "street-legal" added in there. I had to order flanges from racing beat and pick up a piece of 3" SS tubing and have someone make my midpipe. But if I were you I'd just get the flanges and order a Borla XR-1 and a small amount of pipe and use that as a midpipe. I will doing this myself. Its not REALLY loud and I haven't gotten pulled over but its pretty loud for a subdivision.
