A vacuum exhaust cutout, also known as an electric exhaust cutout or simply an exhaust cutout, is an aftermarket automotive modification designed to alter the exhaust flow of a vehicle's exhaust system. This modification allows the driver to control the sound and performance characteristics of their vehicle's exhaust with the push of a button or the flip of a switch. Vacuum exhaust cutouts are often used to create a more aggressive exhaust note and may provide minor performance benefits.
Nice kit, with out the premium price. A must for power strokes. Comes from over seas. Took about 10 days to receive, with good Communication along the way. Going to consider other offerings from SPELAB.
Good material, good prices,
