Granatelli Motorsports 2.50″ Electronic Exhaust Cutout Kit

You're not just building a car—you’re building an experience. Whether you're tearing up the track or cruising the streets, there are moments when you want to let your engine speak. The Granatelli Motorsports 2.5″ Electronic Exhaust Cutout Kit puts you in full control of your sound and flow. At the press of a button, go from stealth to roar without crawling under the car or messing with tools. It’s the upgrade your exhaust—and your build—has been waiting for.

Why Enthusiasts Choose Granatelli

• Built to Last: Machined from 6061 aircraft-grade aluminum, this kit is engineered to take serious heat and abuse. Internal stainless steel butterfly plates and carbon-steel gear drive mean it’ll keep working when lesser kits tap out.


• Effortless Control: Open or close your exhaust in seconds with a rocker switch—no need to hold it down. The Smart-Chip logic stops the motor automatically, protecting it from overworking.


• 360° Adjustable Turndown: Thanks to the V‑band clamp, you can clock the polished stainless turndown to fit your setup perfectly—no compromises.


• Clean, Stealthy Install: Wires tuck easily, and the compact design disappears under your ride. The high-polish 45° tip adds visual punch where it counts.


• Everything Included: Complete with gaskets, wiring harness, clamps, and a switch—just bolt it on and you’re ready to roll.
