Squeaking since catback install

[Spork1569]

I noticed today while driving with windows down that there was a squeaking noise coming from the rear of my car. I wiggled my exhaust a bit and came to the conclusion it was the catback.

My guess being that it's either the new powerflex hangars squeaking or something else from the exhaust. Has anyone had to grease or lubricate exhaust hangers similar to some RMM's? Or could the squeak be from another location in the exhaust?

It's nothing too crazy, nothing worse than the Mountune RMM squeaks without grease, but I'd like to fix it if possible.

Those new hangers are polyurethane, yeah? PU has a tendency to squeak when not lubricated sufficiently, as I'm sure you know. Slather some thick, high-temp grease on those bad boys, inside the holes the hanger rods are inserted. That should take care of it.

Yep that was my guess, i have some lithium grease laying around hopefully that'll be good enough. Guess I have an excuse to get under the car today.

I bought a tube of honda silicone grease for treating window seals, etc. - I added some to the poly bushings on my exhaust and it quieted them down a bit. I also found a high pitched ringing sound coming from the car and thought my exhaust was broken, turned out it was the heat shield around the exhaust. Knock on the heat shield at various places and see if it rattles at all.
