Has anyone tried this on their 350/R? Saw someone in a FB group say he pulled the exhaust valve relay from the engine compartment fuse box and this kept the valves closed and the 350R was able to pass sound at Laguna Seca (90 db).
EDIT: this "solution" appears to defeat all drive modes, which is less then optimal for more experienced drivers. So far, the Grimspeed resistor plugs with pigtails looks like the most realistic solution.
