650 Meisterschaft GTC Valvetronic Exhaust Video dyno video as well!

Hi Guys,

It was great seeing everyone at Bimmerfest!

Here is a short video of my car at Bimmerfest 2012 on the sound of the Meisterschaft GTC Wireless Valvetronic Exhaust with valves closed and valves open.

I have had the exhaust on for about a week now, sounds incredible! No droning of any sort even with the valves open. If you want absolute quiteness for long distance drives you can always close the valves it sounds completely stock. I drive with the valves open at all times just to enjoy the fun and looks on peoples face especially on down shifts haha.

Luigimaster has the same system with the AR catless downpipes on, this video only has the unit with Xpipe back. It should sound the same on the F10 550.

http://www.youtube.com/watch?feature...&v=u7D-JC2T0gc





15hp gain from stock and 20lbs of torque gain from stock!

GREAT THANKS TO
Steve and Tom @ European Auto Source EAS for all the installs for this project and dyno!
GTHAUS John, Jerry, and Mickey for the Great Meisterschaft GTC System
John @ CKS Suspensions
Steve, Vince, Peter @ iForged Performance Alloys
Ken @ Diamond Hills Auto Collision
James @ JL-Motoring for diffuser and trunk spoiler

Alex, sounds nice.
You guys were speaking Chinese in the background. I think maybe people should set up vendors that sell Taiwanese small snacks at the fest next year!! I am sure it will make lots of money.

Yeah, the video doesn't do the sound justice. Mine sounds deeper in person than when I try and record it. Sounds aweseome. Makes you want to get on the gas more.

What's the warranty like on this exhaust? Mainly focusing on the opening and closing of the valves? My buddy used to have a dump valve on his subie and it kept getting stuck every 5-6 months, and he eventually got sick of it and sold it.

Those Dyno results are great. 15hp/20tq gain after exhaust was put on is really good. Did it make a difference if the valves were open or closed as far as performance gain?? Did you feel like you lost some low end tq cuz it was moved to the top of the rpm band more?
