Header Knock
 

He guys, currently running Motive Overpipe, HKS Front Pipe, and HKS Catted EL Headers..also on a Stage 2 Tune..after my header install I've had a knocking sound coming from the engine area..between 2-3K RPM but passed 3K it's not as noticeable unless I lay on the throttle. It's not a exhaust leak, I've had it checked for that, Any suggestions? It's really annoying and sad :(

Maybe your front pipe against the frame?

If the clearance is tight some different motor mounts might help reduce movement.

check ur overripe hitting the sway bar. i know mine did so i took it off, dented it, and problem solved

Header to belly pan. Check your clearance or look for rub spots
