I was interested in getting the Y-Pipe and the Hi-Flow Cat. I was wondering if there is a difference between the aluminized and stainless steal? Is the Stainless steal quieter? Also, I have a Greddy exhaust, will I have to make a conversion from the 2.5" Cat to the 60mm Greddy exhaust? Please let me know.

We don't really think there is any sound difference between either stainless or aluminized pipe. As I mentioned in my email to you if you have your Greddy pipe bolted to your stock cat our High Flow cat will bolt right up.
