hey guys, just outta curiosity, what would cause a sulfur, or garlicysmell to come out of the exhaust. I have 1-1/2 primary headers with a new cat, 3in the rest of the way back. This is on my 86 LG4. I dont have the smog pump on, and the motow, aside from the air filter, is mostly stock. what would cause this?

 

Sulfur is a rotten egg smell. I've heard that it means your cat is clogged, but same thing happened to me when I got my new one, I think they just need to break in.
