Eric says 450HP for the 2-1/2" ID mufflers. I think they'll work fine for you. Bear in mind you can get a little more muffling by making them an inch or two longer and you'd be the only one that knew they were longer by looking at them. As you suggested turning the tips down on a slight angle (about 15 deg) helps some but if you have then going too far down the sound bounces right back up from the road.
