Perhaps I did not understand the process. I also have projectors. I had thought folks were disassembling factory headlights and replacing the projector units.
Looks like I should have come here first, but I might be ok anyway? So I have a 2015 SLT Sierra and thought I was going night blind. I got these without doing too much research, but they seem to have improved matters thus far.

On that note, I had to bring the old girl to the stealer today and removed my Range AFM disabler beforehand thinking they might spot it. Sure enough, first thing they do is plug in, even though it did not need plugging in. Ha! can't catch me though! Range slips under the radar.
Did anyone notice a change in the way they drive once you can "hear" your truck. I think I tend to be a bit more aggressive now. Gotta watch that or Johnny Law will get me.
I am assuming they deleted the flapper. I did not even know it had one at the time, so I never asked. I would crawl under but for two things: its cold and i'm lazy. Also I'm a cripple. Can still do it, but not fun.

Just had it up on I-94. In top gear at 70-75 you can just hear it burble a bit with the windows up, radio on softly, and heat on low-med fan speed. In town or in traffic, has a nice growl. Good rumble at idle.
My local shop just put on a Flowmaster and deleted my resonator using the remainder of the factory stainless and fabbed up the custom bits while I waited. About an hour. $275
