2016 Focus ST
I recently installed a focus sport exhaust system and when the car is turned off, I hear a weird clicking sound. I drove home from a buddies house tonight, pulled up in my driveway, turned the car off, got some stuff out of the trunk and I hear this click click click click coming from what sounds like where the focus sport resognator replaces the stock cat. ANybody know what this is and should I be worried? It went on for a good 10 minutes after turning the car off slowly slowing down. So after hearing this, I took the car for a ride. It runs good and I really only hear this clicking sound after turning the car off. I really don't hear it when it is idling or on the gas. I don't ever remember the stock exhaust system doing this. ANy advice or responses are appreciated. I broke my computer so if anybody responds, I won't get back here probably until tomorrow. If it makes any difference, I have an 06 ST with just intake/exhaust performance wise, the car has 2500 miles, I have had the exhaust installed for 6 days, and it is cold tonight, probably only in the 40's.
