{"title":"Weld-In Electronic Exhaust Cutouts","description":"\u003cp\u003eUpgrade your exhaust system with Granatelli Motor Sports weld‑in stainless steel electronic cutouts designed to give you instant control over sound and performance at the push of a button. These systems work by diverting exhaust flow away from restrictive mufflers when opened, unlocking a louder, more aggressive tone and potential horsepower gains, while allowing you to close them for a quieter, street-friendly ride when needed. They’re ideal for performance enthusiasts who want the flexibility of both worlds. Whether you’re at the track, cruising on the highway, showing off at a car meet, or simply looking to maximize engine efficiency under load. If you’ve added other performance upgrades like headers, cams, or forced induction, an electronic cutout is a smart next step to reduce backpressure and fully realize your setup’s potential. With a variety of sizes, single and dual configurations, and advanced control options available, you can easily find the right fit for your build. Backed by over 75 years of racing heritage and innovation, Granatelli Motor Sports is trusted by enthusiasts for delivering high-quality, durable performance components, making these cutouts a reliable choice for anyone serious about taking their exhaust system to the next level.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e \u003c\/p\u003e","products":[{"product_id":"i-30500955-granatelli-motor-sports-dual-electronic-exhaust-cutout-kit-307522d-stainless-steel-weld-in-2-25","title":"Granatelli Motor Sports Dual Electronic Exhaust Cutout Kit 307522D - Stainless Steel Weld-In - 2.25\"","description":"\u003ch2\u003e\u003cstrong\u003eGranatelli Motor Sports Dual Electronic Exhaust Cutout Kit (2.25″ \/ 57 mm)\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eSKU: 307522D\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eTake command of your exhaust system with precision and style.
