I have a 2013 rt with awd, I’ve had an aftermarket exhaust for about 6 months and have had problems with the clamps and bolts coming loose at the cats. Today I was driving to work and at low speeds I could hear a weird squeak coming from the bottom of the vehicle like bad brakes or scratching glass. Definitely not anything loose by the cats or anything. Any ideas? Please respond this car stresses me out already rebuilt the motor once.

I put a 3 inch dual exhaust on my rt and I had to space the cross members on the bottom of the car (in the middle, where the x pipe would be) away from the car about half an inch or they would rub/vibrate on the pipes and make awful sounds. I’d check there first.
