Hi I just installed a 4-2-1 header on my car and now i notice a faint hissing noise as I gas and there appears to be a little dripping leak where the header connects to the cat. Just wondering if this is normal.

Thanks for your help

did you use a new donut gasket on the end of the header?
Tighten down the manifold bolts (up top) again, some times they need to be tightened back down after driving and getting hot.
