2020 M550 catted downpipes
I've been searching around the forums and youtube for a while, and I'm having trouble finding information on high flow catted downpipes. I've found these two:
https://x-ph.com/racing-dynamics-cat...130-10-63-520/ and [https://store.activeautowerke.com/pr...5-x6-550i-650i Does anyone have any experience with either of these? Know any others? How about performance number after a tune? If there's a thread on this that I've missed, I apologize. I appreciate any help / pointers. |

We offer both; Active Autowerke does not trigger the check engine light. Racing Dynamics does.
Performance is the same with either brand.
