2014 550xi full Catless exhaust

2014 550XI with Active Autowork Catless DP , Meistershaft exhaust, K&N filters.

After the Downpipe install the car feels like a rocket ship! The throttle response is insane. The turbo lag is almost eliminated. I can do full WOT pulls in 4th gear at 60 and it pulls hard! I was not able to do that prior with stock DP as the turbos were not fully spooled. I will be dynoing this week!

I made 481AWHP and 540TRW with just BMS tune on dynojet.
With a full Catless exhaust and filters I hope to be at 500+AWHP and 580+TRQ.
I will be dynoing either Tomorrow or Wednesday.

The Drone is not bad at all. It's just a little loud. I don't mind it because the Sound matches the power which in most cases it does not.

Hoping to dethrown Bad black and crank into mid-high 11s ahhahhahahahhah
We should be doing some practice runs soon.

Yup.. My wife wants to kill me! The new trick is I start he car and slip it right into drive to avoid that loud cold start. And drive away ever so slowly..

What are the specks on those rubbers? They look almost like slicks.

Does adding this exhaust void the warranty? I understand from the cats back is one thing but just curious about a complete new set up such as this.
