Well, it was designed for a port that has uniform cross-section. Flared ports are good for reducing turbulence at high airspeed, but then again, the port on this model is so oversized it'll never even get close. Still, I think you'll probably be OK. Maybe just add 1/4" extra length to make up for the flare. You can always check the Helmholtz frequency when you're done, and if it's between 57Hz and 63Hz, it's fine.
