Installed new Headers need help!!
 

Hey y’all I just installed Weapon R Headers on a 2016 Scion tC, but there’s seem to be a weird sound coming from the Header
almost like a leak, the noise is especially loud at low RPM,

Any feedback will be greatly appreciated.

Sticky Where to Post Your Question

______________________________

Did you torque all the bolts to spec? A cardboard or pvc tube can help isolate the noise. Put one end of the tube to your ear. Carefully move the other end of the tube in and around the noisy area, taking care not to touch any moving parts.

Once you isolate the noise, try tightening the nearest header bolt(s). Be careful not to over torque.
