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. - AdrianG |

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