Take Control—Silence or Roar, On Demand

Instantly switch your exhaust tone and flow with the Granatelli Dual 3.0″ vacuum/pressure‑controlled electronic cutout. This dual stainless steel system gives you aggressive sound when you want it—or stealth mode when you don’t—with a sleek slip-fit design and Smart-Chip motor.

Why It Stands Out

• Rugged Construction: CNC-machined aluminum motor housings with stainless butterfly plates and shafts—built to handle extreme heat and abuse.
• Smart One-Touch Control: Smart-Chip rocker switch with auto-stop eliminates gear strain from holding the button.
• 360° Exit Flexibility: Polished 45° stainless turndowns mounted on V-band clamps let you aim sound exactly where you want it.
• Solid Motor Performance: High-torque DC gear-reduction motor with carbon steel gears guarantees reliable full-open and full-close cycles.
• Complete Kit: Includes everything you need for install—cutouts, Y-pipes, wiring harnesses, switches, gaskets, band clamps, and hardware.
