Performance Exhaust - unusual sound?
If you notice, there's a rattle sound at the end of revs. It happens when the car has been running for a while and is more pronounced when valves are open.
What could be the reason for it?!

Totally normal. That's a characteristic sound of the PE haha. People pay for that noise.

I think I have that also but never thought of it as an issue.
What does bother me is this clank sound I get from the exhaust after some spirited driving. Happens every 3 seconds even when car is off. I know it may be metal/heat related but it starts even while still driving lol.

You don't know how truly lucky you are to have that sound. Children in Africa are driving with the standard exhaust!
I have to say, your exhaust sounds very nice. Those belches and resonances give the car a personality, albeit an obnoxious one. Every noise is connected to something happening inside. That metallic claps are the flaps closing, the burble is backpressure. They remind you that you are in a machine.
