      SKU: 302540
      Take total control of your vehicle’s exhaust tone and flow with the Granatelli 4.0″ Oval Electronic Cutout Kit. Designed for high-output builds, this all-in-one system gives you the freedom to run quiet when needed—or rip wide open at the push of a button. Built for those who demand serious performance and bulletproof reliability.

      One-Touch Smart Control
      Precision CNC-machined 6061 aircraft-grade aluminum housing delivers strength without the weight.
      High-torque Smart-Chip DC motor provides smooth, responsive actuation with auto-stop to prevent gear strain or overtravel.

      Massive Flow. Deep, Aggressive Sound.
      Built for 4.0″ (102 mm) exhaust systems—the oval-profile butterfly valve ensures minimal restriction and full flow when opened.
      Includes a 45° polished stainless turndown and oval-to-round adapter, secured with 360° V-band clamps for clockable fitment.

      Everything You Need, Right in the Box
      Complete install kit: turndown pipe, adapter, V-bands, gaskets, switch, wiring harness, and hardware—no missing pieces, no guesswork.

      Engineered to Take Abuse
      Corrosion-resistant stainless butterfly valve and shafts stand up to the elements and extreme temps.
      A heat-rated carbon-steel gear train is built for high-cycle operation, even under full-load punishment.

      Why It Dominates
      Flip the switch for stealth mode or wide-open roar—perfect for the street, track, or show.
      Heavy-duty construction resists wear and abuse from daily driving or hardcore runs.
