Message	He was talking about replacing already-gutted pre-cats with downpipes. There's not THAT much difference in airflow restriction...he's not going to see any significant HP increases. Maybe 1-3hp on the dyno, and you know as well as I that such variances can show up in multiple dyno runs anyhow. It certainly won't be anything he can feel.
