Default Exhaust

Setting up a new boat. Putting in a 565 with 695 horsepower.

I have the hardin top riser style exhaust. My boat builder suggested these were a great set of manifolds.

After looking on the web though their site reads great for motors up to 450 hp.

Does this mean I should get something else??? Will it noticeably kill my performance??

ANy help would be great....
