This is an exhaust clip of my Mustang before i fixed it. It was running on 7 cylinders in this video which is why it makes that backfires and it smokes. The rocker arm came off one of the valve stems and had zero compression on cyl 8.
Flowmaster 30 series mufflers with stock exhaust
Now has Flowmaster 40 series.

could just be your exhaust setup or your car is running too rich, I have a gto now and it pops like crazy when you left off the gas but it is running rich because of its tune..
