Thanks! Additional info is you can remove fuse #35 right in the left side trunk fuse box listed as the "Exhaust valve fuse" in the owners manual, and in my 16' ATS-V listed as "spare" on the fuse box lid. This will leave the valves open in all driving modes and all speeds...no dash lights or warnings. Now I have to see if it works in My 16' ZO-6.I wanted to let everyone know about a trick that a friend of mine showed me. If you want more sound all of the time from your ATS-V, all you have to do is unplug the connectors on the exhaust valve solenoids and that will keep the valves open all of the time. This will also allow you to drive your ATS-V in any mode and enjoy more sound.
