Hello everyone, I’m new to the BMW family. Came from a q60 redsport. I’m looking into modding this vehicle soon. Hopefully you guys could help
I’ve read that downpipes usually throw a CEL. Would I need a universal 90deg o2 extension to prevent that ?
And as far tuning it what do you guys recommend ? MP, gintani , BM3 ...JB4?..
All info is appreciated!
