^Nice work
I know the following question has been covered 230598475 on bimmerforums, but I want to ask the Momentum guys from experience they have seen on their customer's cars.
For N55 2015:
JB4?
Dinan?
Other?
The car is stock, and I am not looking for anything crazy, stage 1 is fine.
I also know BMW laval does Dinan and maintans the warranty with it installed
Recommendations?
(As for anything more than Stage 1, I'll probably change cars before I upgrade the downpipe, exhaust etc, so I don't think its worth it in my case)
