Hi guys,

I just started to notice when i stop at a red light after some driving i can hear periodic click/pop sound coming from underneath my car. I can also hear the same sound after I drive and park my car. Is this normal????

thx

yeah its the cat... its most noticable after you shut your car off. I just installed a test pipe and I dont have the sound anymore.

Yea thats normal it is the expansion and contraction of metal due to heat, it tends to come from the cat due to it's internal design, which consists of many smaller metal pieces.
