its pretty common for these cars to pop alot when the rpms come down after you put on a cat back. less back pressure, and its louder so you can hear it more.

nope the lt1 does it naturally ... getting a tune could help it out ... you might be running a bit rich. even a perfect a/f setup with still have some pop.
