Loud ping

[OrientExpress3]

I got a question, sometimes when I start my car I hear a loud ass ping noise. The only mods I have are intake and exhaust, sometimes the exhaust makes this loud vibrating shaking noise. Does anybody know what this might be? Please help!

why dont you have a buddy or girl friend start the car when you are looking at the engine to find out what it is?

Could be your intake hitting a piece of the frame, when your car starts up the engine torques back pulling the intake.

I know some people have posted some pinging / tapping sounds coming from the engine and said the noise was gone after putting in some 5w-30. Not sure if it's the same sound you're experiencing. Hope this helps.
