This is just a shot in the dark but your "clicking" sounds may more correctly be "pinging" sounds from the thermal contraction of the exhaust system as it cools down. The exhaust system gets incredibly hot during normal operation and the catalytic converter gets even hotter. As the exhaust components cool down after running, it's normal to hear some occasional "clicking" sounds. Any decent mechanic/technician/enthusiast should be able to identify if that is what you're hearing. If it is, not to worry. It's just physics at work.

Lotsa luck.:iceslolan
