Squeaking noise after exhaust install

[Thefunk]

Every time I go over a bump I hear a metallic squeaking noise, particularly from the rear. Where do I check for squeaking? The hangers? The pipe joints and clamps? Also what kind of lubricant should I use for the hanger bushing?

I've been having this issue as well, and I haven't touched my car in terms of installing new parts yet so it might be an issue from factory I'm not sure?

No the exhaust is the Nismo Track exhaust.

It's possibly rubbing on a heat shield. Make sure everything is straight (flanges and gaskets) and the piping has good clearance from the walls.

I meant the squeaking noise might be a factory issue, I don't think it's an install issue is what I'm trying to say. According to another thread, it's probably your door actuator.

Really? I should record the noise and post it. I've been trying to isolate it and it sounds like it's coming from the passenger side, and the squeak is a high pitch, lite metal sound. It's not a squeal like brake rotors squeal, but a metal-on-metal squeak. Another thing I noticed is that there's a very short delay between going over bumps and the squeak, leading me to believe it's the exhaust.

mmmm maybe it's different than what I'm talking about. I just been having some squeaking happening when I go over bumps too and it's driving me nuts

The exhaust gets close to the triangle rear brace. Check clearance there.

If you grab the exhaust pipe while the car is one ground (AND IT IS COOL), can you wiggle/pull the pipe and recreate the sound?

Yes and no. I tried that once by just shaking the exhaust tip and there was a quick squeak then I couldn't reproduce it. I have to get under the car at some point this weekend. I've also been getting creaking noise when going in reverse slowly, like when I back up into my driveway.

This is unrelated to the OP but
I've been trying to find other examples of this creaking sound and found a spot on video
