We have this

Just downpipe connection. That is the only difference, that Im aware of, we will find out shortly.
I will have the tune on my car and wont be able to take it off.. 
But I will have a Tuned dyno, and a Full exhaust dyno after for the Stage 2.
Don't want to get into all that here though, so please pm me if you have questions, I want to keep this on topic. |
Agreed. It should give a power gain, not only flat spots, but narrower diameter too on the oem one. Can't you just take the tune off in 2 minutes? It's two connectors, easily accessible like on Arch's car. If not, I think we can compare with your other dynos, right? Or were those with downpipes?
Either way, someone will hopefully dyno test the before and after and will show the gains. I've driven a 550i with mull Meisterchaft exhaust - hard to quanitfy if it felt faster but it certainly felt smoother and sounded incredible.
Good work.
