I remember watching TrucksTV last year, about mid process of the Copperhead build-up that Stacey brought out electronic exhaust cut-outs. Basically you wire up a switch in the cab and when you hit it, the exhaust bypasses to open headers. I tried seaching on the internet and on TrucksTV.com, but I can't find it. Do y'all remember what company makes them or where you can find them? I'd love to have them on the 383 and uncork it at a redlight.
