Exhaust Vibrations

[Reuben911]

My 911 3.2 has an exhaust rattle when the engine is hot. The rattle is only noticeable when slowing down and when there is no load (feet off the accelerator).

I think it is the muffler, is there any isolation material I can use between the muffler straps and the engine mount cross member ?

Sound like a metal on metal vibration.

Any ideas ?

Have you had a look under there?

Yes! If you still are running the factory exhaust setup with the cat, look for a loose heat shield.

It's an aftermarket exhaust

Will take to my local exhaust shop for a closer inspection

loose internal baffle?
