Exhaust popping?

Here's the situation. Stock 99 Camaro SS exhaust.

After the car warms right up and I run it for a while, when I stop at a light (idle), the exhaust makes distinctive "pop" sounds. This only happens after the car has been run and only at idle.

Any ideas/suggestions? Possible exhaust leak? Car running rich?

Any help would be apprciated.

THANKS!!

Re: Exhaust popping?

I believe that this is gas igniting somewhere downstream in the exhaust(possibly the cats). The way I read your thread was that the sound was probably similar to what people experience when adding a catback. My GMMG pops when I let off or rev down while still in a gear.

I don't think there is anything wrong, but I'm curious to see what others have to say on this.

Re: Exhaust popping?

I love that sound, and the only time it happens is when I first start up the car. If I rev it, it will pop. The only other time it happens to me is the first time I shift 1st to second.
