I have had several different sets of electric cut-outs on my cars over the years. Every set of butterfly cut-outs I have seen, leak. I have an older set of the Doug's on the Cuda now. They were expensive and are bulky. But they have taken a beating and still don't leak. Is it true that Doug's changed their design and no longer make that guillotine or sliding style?

Electric cut-outs are a blast. I use them more around car shows and cruises than at the track. I'll never have another muscle car without them.
