Awful rattle sound when on/off throttle!

Hello everyone I am hearing this awful rattling sound coming from the driver side of the engine bay and i can't figure out what it could be.

It happens when I'm getting stepping on the throttle and when i start letting off..

It started right after i finished a 3-5 min spirited run.

I recently installed coils a week ago

UEL header 3 months ago

OFT 6 months ago

I think it may be my header i knew some bolts weren't tightened down enough and i never got back to them.. any help is greater appreciated!


Update! Was driving on the highway and my car had died on me (not stalled) I couldn't get it to turn back on it's not cranking over. All my electronics on my dash are wonky and key fob or windows won't work.. got a tow and tried to jump start, it turned on and ran for a few making terrible noises so I turned it off and it drained the tow guys jump start machine.

Really bummed out and excuse my terrible attempt at trying to explain what's happening


Update#2 car is completely dead. I won't start and no electronics work at all.. going to try to flash to stock some how and tow it to the nearest dealer about 3 hours away.. :(

well if anything you already maybe solved the issue, get underneath the car and check the suspension for loose bolts, then check header bolts if that doesn't solve it.

sounds like exhaust leak

DANG! ,Dreamzqt .....you know what has to be done ....... just do it .......;)

What kind of terrible noises .....??

Are you sure the battery is charged up to full capacity ..... ??

Can't really describe it.. it was just really loud rattling.

And I have no idea about the battery's charge

To check your battery you could take it into a shop or .....invest in a volt meter and check it yourself .....;)
