Right now i have stock y pipe and bassani cat back. theres no raspy noise. I had the sho shop cat less y pipe on and noticed a performance loss from not enough back pressure. There is a raspy noise but its not that bad or loud. I like how the bassani sounds with stock y pipe then cat less y pipe though. I'm not sure if you get a chip custom burned for no cat if there would be a performance loss, anyone know?
