I got this too, from the beginning. I have BRZ S '16 with 53,000km. My house mechanic told me maybe we need to exchange the CAT with the manifold as I already let them switch the lambda but to no success.

Does anyone know if a 2018 GT86 Toyota cat with manifold fits for a 2016 BRZ S perfectly? I could get one below 300€ from an online site.

Thanks for the info in advance and best wishes!
