ok so. . .

i hear this noise when i rev my engine and its just like clicking or tapping whatever its there. sounds like the header gasket i think. i just wanna be reassured. or if its some other common problem. there was another tap click coming from the header to cat gasket and now its silent. so could it be the header gasket?

HELP!!!

 

sounds like it could be a crack in the manifold

jack it up have a look

use jack stands

 

it could be the precat also.. mine used to click and tapped but i just put on a new header since i was getting rid of the cat anyway...after that, no clicks and taps

 

It may be the linkage for the port actuators. They can get loose and create a tapping or clicking sound. I only say this because it happened to me.

 

i have a RB header. so could it be a crack in the header??? or the gasket to the header??

 

how would i fix the tapping noise from the actuators?

 

Replace the linkage. Or possibly duct tape it or something lol.

should be fine
may also be a heatshield somewhere
get rid of that shitty air cleaner... run the stock box - it sway better designed. you wont increase flow like that, but you will stop sucking in hot air

and put the fan shroud back on.
