If your exhaust tips aren’t all even then most likely your exhaust hanger bushings are shot (you can look through the diffuser vents to check them quickly) The original parts are discontinued and people sell old broken used ones for crazy prices on ebay.

I offer you a nice quick 10 minute repair kit. Just trim out all the broken rotten rubber and slide in my bushing then bolt it back up. no adjustments needed. Material is a strong wear resistant plastic known as PETG with a melting temp of 482 Degrees, so you don’t have to worry about them melting down on you.

One kit will fix both exhaust bushings
