iv asked in other places but i just want to get all my information. most of my sound is coming from either where my header connects to my motor or where my header and downpipes meet. Its making kind of a clicking or ticking noise. Basically it sounds extremely rice.

How can i fix this? if i can.

Im putting on my right now, did you use the factory gasket? Because my does not fit at all...and my header itself had a grove running across the length of the header face (where the gasket goes)...Maybe it has something to do with that? If yours is the same as mine.
Either way, im betting mine will leak.

i took it back down to my local chevy dealer and they fixed it, was a exhaust leak. I originally thought that but would have thought they woulda noticed that when they put it on.
