High flow cats

xito_a · 06-07-2023, 09:14 AM

I was wondering if anyone knew any good high flow cats for a 2014 650i xdrive gc. I looked at Vrsf but couldn’t find any high flow (only fully catless) cats from them and don’t know any other brands as well.

Also wondering if they’re worth it, I know I can go stage 2 with it but lowkey worries about smell and legality of it (I’m from Ontario which is strict af)

I believe AR Design makes some. Planning on going with them in the future for my 6 series.

On my 535i I currently have an ER Performance high flow downpipe. With a stage 2 tune I do notice a bit of an exhaust smell, but nothing extreme.
