Additional Information

Doug's ELECTRIC EXHAUST CUT-OUTS The original Doug's Headers has announced a New and Improved version of their popular all stainless steel construction electric exhaust cut-outs in 2 1/2" and 3" diameters. The engineers at Doug's have taken their famous electric exhaust cut-outs and dramatically decreased the size for more versatile installations while lowering the price as well. These cut-outs feature a rugged gear reduction 12 volt DC motor and a rotating gate for a leak-proof seal every time the cut-out is opened and closed. Unlike butterfly style cut-outs the Doug's cut-outs don't have the leaky gasket sound and when fully opened there is no exhaust flow obstructions. A pre-wired harness with an illuminated rocker switch is supplied for easy installation. Un-cork your exhaust with the flip of a switch from you dash. The cut-outs are ideal for race tracks that don't require mufflers. These Doug's cut-outs are available in singles or pairs and in complete kits with Y-Pipes for easy installation
