Not so much of a problem, but more of a question. When I look at my car from the rear (my favorite view by the way) the exhaust tip that is second from the left is slightly higher than all the rest, NPP exhaust. Since both pipes on the left are in the same muffler, is it possible to somehow rotate the muffler to bring that exhaust tip down or is there another way to bring the tip down? It is not terribly noticeable, but my daughter pointed it out to me, so it is obviously noticeable.

That is not acceptable, I would be at the dealer getting that fixed

Thinking out loud here, but (as you state) since the left two tips are attached to the same muffler, rotating the entire muffler such that the inner left tip lines up with the right tips will raise the outer left tip...and it will still look out of alignment...I would think just the inner left tip needs to be bent down slightly....

somewhere here or other forum (modshack, maybe) reported it was a bad weld...you can get the dealer to do it but they are not as expert in breaking the weld and rewelding as a good muffler shop, that can probably do it for $50...

I need to go verify what I think I know but it should be quite simple to do.
Loosen bolts between the 2 pairs of tips, loosen V clamps ahead of rear axle, rotate muffler assemblies into correct position. Tighten bolts between tips. Verify they are aligned to your satisfaction, tighten V clamps. Or have the dealer take a shot at it.

Just got back from the dealer, I talked with the tech, he insisted that there was not a way to make an adjustment. Was told it would need to have a new exhaust put on!! I was running late for an appointment so did not pursue. I will look at doing it myself as suggest about by Dasyatis.

Mine does not have any bolts or clamps between the tips. There is a clamp between the two mufflers but it does not appear to have much or any wiggle for adjustment. This clamp is behind the tips. I do t see how I could make an adjustment to the tip angle.

Also dealer had a LRG premier vert on the sales floor. It also had the same issue. Most likely I will live with this issue, at least for now.

After reading this thread, I have been looking for this now in various pictures, and have already seen it a few times, even on random pictures people have posted just to say, "Look at my car."

Here is a pic of 4 C7's lined up and not one of them has a misaligned pipe so don't let the anyone tell you they are all like that.
It's difficult to tell with certainty from this distance, but to me it looks as though each car has the misalignment.

The 2nd pipe from the left (driver's side) seems to be the issue. It looks a bit high for all the misaligned cases I've seen so far.

Tolerances on exhaust systems are typically very large, and the exhaust system expands substantially when heated, so it wouldn't surprise me if this misalignment looks different after the car has been parked overnight versus after a nice high speed run.

I can't really see that on any of those five examples except maybe just a little bit on the Arctic White.

By the way, we know that area will never be always perfectly aligned (to a tenth of a mm, for example). The question is how much misalignment is too much? I would say very few cars would have misalignment to the point that it would be noticeable by a casual observer not specifically looking for it.

On the other hand, it is extremely interesting that it seems to be always the same pipe misaligned, and that, if some misalignment is perceptible, it is always high instead of low. I bet that if GM knew this were happening, they easily could go find the source of exactly what is causing this. I also bet that source is one people would have never guessed, and it might actually be quite funny.

Here is a photo of the red vert close up, you can see that all of the pipes touch the level the same.

I live in the Gulf (Dubai, United Arab Emirates), and my Z51 had exactly the same problem!
I took it to the dealership, and they said it is different from the C6 exhaust mount.
They tried loosening the two bolts in the middle, and then they loosened the exhausts about 3 ft towards centre of the car.
It looks better now, but not exactly perfect. They inferred that it was bad welding, which they could look into whenever I bring back the car.

I would put it up on a lift, measure each height with a transit or builders level, then put the laser line at the top or the bottom of each tip, then perform the task as Dasyatis stated, that way you know the alignment of the exhaust will be to your liking.
