Granatelli Motor Sports - 3.5" (89mm) Slip-Fit Electronic Exhaust Cutouts

If you have a high-horsepower build, then the 3.5-inch slip-fit stainless steel electronic exhaust cutout is for you. Its 89 millimeter diameter gives you all the airflow you need for your high-performance demands. It’s the premium choice for racecars, supercharged and turbocharged street builds, or any exhaust system upgraded to 3.5-inch tubing.

 

You can customize your exhaust system with the flip of a switch, thanks to Granatelli’s One-Touch Smart Control. With a single flip of a rocker switch, the butterfly valve opens fully to bypass the muffler and unleash the complete, unrestrained exhaust character of the engine, then closes again just as quickly to return to a quieter, street-appropriate note whenever the situation demands it. This means you can completely customize your exhaust’s sound and flow from inside your car.

 

Granatelli Motor Sports also uses top-tier materials and design. The round-profile butterfly valve gives you the least amount of restriction for full air flow. The use of precision CNC-machined 6061 aircraft-grade aluminum housing is lightweight yet strong. This exhaust cutout is guaranteed to handle the high-performance situations you crave.
