Was trying to get a valved KKS exhaust bit could not get one , went for an RPI which sounds great when you want to be “on it” but it would be great to switch it off.
Anyone know of valved :?straight through options ??
You can get just the valve & controller to fit to almost any exhaust.
For example, this is £78:
Of course, you wouldn't have it as shown there with a straight cut pipe, it would connected at a bypass so that it either goes straight to the back box when open, or via a silencer/muffler when closed.
