Granatelli Dual 3 Inch Electronic Exhaust Cutout System

SKU: 309530K

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.

Roar Freely—Cruise Silently

Perfect for muscle cars, turbo builds, or daily drivers needing toggled tone control. Rugged, smart, and built ready to roll—this kit offers true exhaust freedom without compromise.
