Hey, since i have put my header on, it seems that either it has caused or it has magnified a "clacking" sort of noise, i am not exactly sure if that means sticky lifters or what.

Should I be worried, or is the aftermarket header just amplifying engine noise, and i shouldnt be worried. it didnt make the noise b4

what kind of noises did everyones header cause?

thanks!

 

ttt.....just tell me what sounds your header makes

Does it sound like a metal on metal noise? Perhaps the header is hitting the heat shields.

 

no, its like a clack or tapping noise on every rotation of the engine

 

its not a heat shield thing

what does a knocking engine sound like? do i have sticky lifters?

 

ttt help pleese

 

Does the noise persist or does it go away after some driving?

I recently installed an A'PEXi header and after I installed it there's a rattling noise that occurs on cold starts, but only if I go downhill, never when I start going uphill, but it goes away once I hit the first stoplight by my house.

I think it's heat shield related, but I haven't gone underneath the car to check/remove them yet, waiting until the upcoming oil change.

Did you torque the nuts to specifications when you installed the header?
