No you're not going to 'lose' hp perse, you might lose some low end torque but probably gain that in the higher rpms.
What that does is basically push your torque at a higher rpm, so you may lose some but you gain it back somewhere else.
Though putting a nice chambered muffler instead of a straight thru one will keep some of that backpressure in the exhaust even with a bigger diameter. So you get the best of both worlds, more flow due to the 3" pipe and backpressure due to the more restrictive muffler.
