I would put the stock cats back on if I could. But with the amount of boost im making I would melt them into lava.

I had the exact setup you have, with the berk hfc's and all. I opted for the motordyne ART pipes as I needed test pipes and these are supposed to be the quietest of any resonated test pipe. They definitely are not louder than the berks. It was hard to compare since I put them on and then didn't drive my car for 2 months so kind of forgot how it sounded with the berks on there for a comparison.
