Ticking sound from exhaust

I have a Corsa exhaust on my A4 05 and it been installed for over a year now. All of a sudden, I'm noticing a ticking sound coming from the rear end once I park the car after driving it. It's almost as if the metal back there is cooling down, but this never happened before. Is there a problem here, or is this normal?

I have heard this on all my cars exhausts including my 05'. Especially in cold weather where the pipes are hot and the weather is cold as the pipes cool down.

I wonder why it didn't do it during the first year I had the exhaust on?

Check to make sure you have no fluid leaks anywhere. I had the same thing happen on my 88 Chevy P/U awhile back. Had a oil leak and when I turned off the truck the slight drops of oil hitting a hot pipe made a ticking sound

then it just might be a hot pipe cooling off in cooler weather as stated by
