Only right side of exhaust is working



I only loaded BM3 Stage 2 AGG to test this out. As you can see, the flame only comes out of one side. I've set it to open in the config, and in bimmerlink. Am I missing something?

Im pretty sure this is bc the right side is a shorter pipe so it tends to have more flow in comparison to the left side

That would make sense. So even if the left side pipe doesn't get as dirty... you think that they are still both working?

Yup, the exhaust gasses are just taking the path of least resistance.

You can look up the left side and see the valve inside, just make sure it's opening and closing
