    Thank you I took it to a garrage and it looks like the honeycomb inside the catalytic converter was rattling and causing the air not go get out quick enough. Would you recommend cleaning the egr valve and pipe too

    No. The Gen 2 does not have those. You might consider cleaning the PCV valve though but I would bother myself unless you have reason to believe it is sticking.

    The CC installed is not good enough. Presume it is not an OEM CC.
