    I disconnected the exhaust valve vacuum lines in the R engine bay. Described in the valve disconnect thread

    interesting I would think the more free flow of the exhaust from like 4k to redline would be a benefit. I know I feel the need for some back pressure in the lower rpm range. Might just be what I've seen with a aftermarket exhaust.

    There is NO power loss. It rips. Same on a gt3. You unplug the valves and get more smooth and instant power delivery. See below dyno on a gt3 from obsessed garage, top curve is disconnected valves. The gains arent this big on the R8 but the stock muffler provides enough restriction to get gains. It sounds glorious too. Valves are for VWs

    Is this for a V8? My dyno was much higher on a v10 before a supercharger was put on.
