In this video I discuss the Grimmspeed exhaust valve simulator plugs for the Shelby GT350 and GT350Rs. A buddy of mine installed them on his GT350R and after driving it I knew I had to get a couple for my car. I'd highly recommend them if you never find yourself closing your valves. No more toggling the valves open on start up, having a quiet 6th gear, or a quiet rev-match from 6th to 5th. The way it should've been honestly. Thanks for watching!
