The AMS catted downpipes will add sound but it won't really add any horsepower. When I said "won't really" because you MIGHT get 2-5hp out of it but even that is questionable.
In general high flow (AMS catted) or catless downpipes (straight thru) will allow other modifications to work more efficiently while used in conjunction with the high flow or catless downpipes.
