Like the gas isnt all igniting in the cylinder, so it pops in the pipe. Is this bad? How can I make it stop if its bad? I was reading something and some one said it was bad when it pops in the pipe. Maybe they were wrong.

Are you talking about the normal pipe pinging? Sounds kind of "tinny"? This is simply the exhaust gas expansion.

 

Popping can be a sign of a lean condition.
