Mild Steel Electronic Exhaust Cutouts for Instant Sound & Performance Control

Looking to unleash your vehicle’s full exhaust note at the flip of a switch? Granatelli Motor Sports Mild Steel Electronic Exhaust Cutouts provide an easy way to bypass restrictive exhaust flow when you want maximum sound and performance, then return to a quieter street-friendly setup with the touch of a rocker switch or Smart-Chip control system. Available in 2.25", 2.50", 3.00", and 4.00" diameters, with both single and dual cutout configurations, these slip-fit designs simplify installation by eliminating the need for welding on many applications, making them a popular choice for enthusiasts seeking a straightforward upgrade. Featured options include the 303522D 2.25" Dual Electronic Cutout Kit, 303525 and 303525D 2.50" kits, 303530 and 303530D 3.00" kits, and the 303540 and 303540D 4.00" kits, allowing you to match your exhaust system size and performance goals. Common signs that an exhaust cutout may be failing include slow actuator response, intermittent opening or closing, unusual noises from the motor assembly, exhaust leaks around the valve, or a cutout that becomes stuck in one position. When properly functioning, electronic cutouts deliver on-demand exhaust control for street, strip, and performance applications. For decades, Granatelli Motor Sports has earned a strong reputation among racers and performance enthusiasts through American-made innovation, quality engineering, and proven high-performance products, making their electronic exhaust cutouts a trusted solution for drivers who want greater control over their vehicle’s sound and exhaust flow.
