96 Impala SS, 383 stroker, LT4, BBK headers. When I step hard on the gas I hear an anoying crackling sound coming from the headers. I almost 100% sure that I have a header leak. Sometime I hear the the crackling sound when I make a sudden stop. Could this be pieces of the gasket inside the headers? Please help

Check for broken/missing header bolts. Headers should be re torqued every month or so otherwise they can loosen up enough to cause leaks/broken bolts. The sound you are hearing is likely a leak caused by gasket failure do to the bolt issue.
