Has anyone had a check engine for cat efficiency after installing cvf inter cooler and down pipes? Also installed thermo rd exhaust.

I'm guessing install error or something with the gaskets.

Okay. I replace the gaskets with the ones that were sent with products. And installed the defoulers. And they could only be installed in the top holes / upstream sensors. What could have I missed

Downstream sensors are used for cat efficiency. Guessing that is where your problem is.
