AAM hi flow cats 400.00 for FI cats for 500.00 are they worth a 100.00 more? Do they make more power, better quality or just sound better, anyone really know?

Running tomei expreme pipes. Wouldn't recommend them unless you're going forced induction. Heard a lot of good things about FI cats though.

AAM uses a 200 cell cat, so had slightly better performance than 300 cell FI cats. When I was ordering my FI exhaust, I met 2 people within a few weeks that had problems with their FI cats and 3 with AAM with no problems after several years. Was enough for me. I'm running AAM cats with FI exhaust.
