There are lots of electrically-operated exhaust cutouts on the market. There are precious few that have all of the features Granatelli Motor Sports’ Dual Electronic Exhaust Cutout Systems do. Let’s explore them, shall we? One-Touch Open and Close Switch Some exhaust cutout systems have an activation switch that must be held down to open and close the butterfly plates. That can lead to overtorquing the butterfly shaft, which can damage the internal gears of the drive system. The Granatelli exhaust cutout systems have a digitally-controlled, one-touch switch to open and close the butterfly plates and prevent overtorquing.

Taylor’s Universal-Fit Spiro-Pro Ignition Wires are a great choice for both street use and racing. The 8mm wires have a stainless steel spiral-wound core that has 10 times less resistance than OEM-style resistor core wire. That means you get maximum spark energy at the plugs while protecting electronic ignitions, on-board computers, audio systems, and pit radios. And because they’re universal-fit, you can cut them to the exact length you need. Other features include: • 8mm silicone outer jacket rated to handle 65,000 volts and provide heat protection up to 600 degrees F • Silicone inner core provides added heat protection and superior flexibility • Low-profile Silicone Pro Boots keep the wires away from your headers • Stainless steel double-spring spark plug locking terminals won’t vibrate off • Available in a choice of spark plug boot end styles • Your choice of black, red, or blue jackets Spiro-Pro Universal-Fit Ignition Wires are also available in a Pro Series with your choice of a resistor core rated at 3,500 ohms of resistance or a solid copper wire core rated at 3500 ohms of resistance. The solid core is recommended for race cars with magneto or points distributor ignitions and no onboard electronics.
