Mike,
The lip shouldn't be a hard fix. If it is flexible you should be able to straighten it with a heat gun. If you are worried about damaging the new paint take it to a body shop they really should be able to fix it. Even if it costs a few bucks, I'd be inclined to get it done because I know I'd keep looking at it.
As for the exhaust beaner, I don't want Mike to get all upset again but it is my understanding that it is not a Galant specific exhaust and it isn't supposed to hang like that on this car. I know Mike is passionate about it but I'm not sure if it is just the sound he likes or if he really likes it being at an angle like that. If it is the latter, I think we will all have to agree to disagree because he clearly has no intention of getting rid of it.
If however Mike you just don't want to lose the exhaust, given all the work you have done on the car, haven't you considered going to a good exhaust shop and having them put one custom bend in the exhaust so that it sits straight and tucks up better? Everything else aside you would gain a ton of ground clearance and probably be able to protect the new paint on you rear bumper as well.
I really don't want you to get upset again. The car looks super clean and you deserve to be proud of it. It's just strange that when you have such a good eye for what makes the car look super clean and original that you wouldn't want to sort this out. I get the feeling you just don't want to back down now because people have given you such a hard time over it.
