As they said banshee used to sell them but they may ahve gone out of business. Partshopper.com used to sell them as well. Just do an internet search for "Banshee Ram Jet" and you might find a vendor. If not you may have to jsut modify the CDC shaker if you can...but it's all a lot of money. Here's my brother's car with the shaker, IMO it looks good and it added a bit of performance.

My brother got his to work with his explorer intake as well as his stock intake because the mounting points were the same on top. The '93 cobra upper most likely wouldn't work without some massaging of the lower shaker box.
