first time at track car got 10x louder after first run

Went to the track for first time with the FBO 335i i took of the backend flash because it was acting funny and not hitting target boost. i have about e30-e35 in the tank on map5. How does this look? This was my 3rd gear pull. For some reason my car go 10x louder exhaust after that run. Does it look okay? exhaust is not much louder and a bit raspier. I have the dinnan FF exhaust.
