After all, you can't have the impulse engines coming from a plugged vent.
You mean TNG, DS9 and Voyager. Since all versions of the Nebula-class; the original "Phoenix" model, the updated "Sutherland" model, and the CGI Galaxy-class based "Bonchune" model all omit the impulse grille.

It seems highly suspicious that all three variants don't have the normal impulse glow, especially since the CGI version was built out of the CGI Galaxy-class made for Generations. It seems really odd that they forgot it each time a new Nebula model was produced.

Star Trek staff illustrator and technical consultant Rick Sternbach, who refined the second Nebula-class shooting model, mentioned over on Doug Drexler's blog a possible reason for the lack of visible impulse ports:

"One of the rationalizations I imagined ages ago for having no obvious impulse grilles involved capturing and compressing the impulse fusion reaction exhaust and later releasing it from special non-propulsive ports. If the Nebula class was employed in a stealthy surveillance mode, it would be smart to minimize all overboard emissions. Since most all "modern" impulse engines involve little or no pure rocket thrust, but more of a sub-warp drive, one could say that the familiar orange Starfleet glowy exhausts could be modified or eliminated."
