I have had my EB mustang since Feb. 2015. I had my downpipes installed in the summer of 2015 and it is catted. I have never had problems with it. Late this summer I began to hear a pinging/rattling sound when I push down on the throttle hard and when the turbo gauge hits 20 (it either hits 20 or looks like it hits 20). I took it to Ford and they said I should use better gas which is bullshit because I only use 91 octane. I took it a second time and they said they don't know what it is. A month or two after this pinging/rattling sound I had a cylinder head and gasket break. So I took it to Ford and they gave me a new engine, this was done in September 2017. The rattling/pinging sound was still there after they gave me a new engine. Three weeks later after I broke in the new engine and was very careful and fragile with the car, but then after accelerating a little fast (did not get to 100 mph) the same thing happened where a bunch of white smoke is coming out the back and a cylinder head broke but idk if it is the same one or not.
Basically I want to know what is the pinging/rattling sound and can a downpipes be the cause of my engine problems and cylinder head breaking?
Thank you and I am new to the forum.
