My Chevy I used to own started doing that once... it was my cat.

make sure the connection from the header to the cat is tight. that connection is held together (on my car atleast) by 2 bolts w/ tension springs that look like valve springs. Check those and make sure they are tight...don't tighten them too much thou. I snapped one tightening it after i put a header on my car. Took my like 5 minutes to find where the spring went. Found it about 10ft behind my car lol.
