3.5RL

Hi, I just installed Magnaflow muffler two days ago( well I had it on my car before, but I took it off like a year ago. Now I had it on along with a new 12" aftermarket resonator in place of the OEM resonator). I hear a tick, tick, and tick sound from the muffler after the car turned off . The sound last for 2-3 mins and it only happened when the car is off, when the car is running there is no tick sound. Is it normal? I just thought it is the metal expanding due to the hot temp. or it just cooling down. Any idea, should I be worry about?Thanks.

Ok, I was wrong. There was a little tick sound coming from the muffler and resonator area even with the car is running, but the tick sound is very low compare after the engine is off. I'll drive for a few more week and hope it will fade away.
