Convert Round Exhaust to a Lower-Profile Oval Design

When traditional round exhaust tubing creates clearance problems underneath a vehicle, switching to an oval exhaust profile can provide a more practical routing solution. The Granatelli 313533 adapter creates a transition from 3-inch round exhaust tubing to 3-inch oval tubing, allowing builders to continue with a low-profile oval exhaust system.

Improve Exhaust Ground Clearance

Exhaust clearance can become a major challenge on lowered vehicles, air-ride builds and custom chassis. Converting from round tubing to an oval exhaust profile allows the exhaust to occupy a different underbody footprint and can help reduce scraping.

The 313533 provides the transition point between a 3-inch round exhaust system and Granatelli's 3-inch oval tubing, adapters and bends, making it easier to design an exhaust system around available chassis space.

V-Band Connection for Custom Exhaust Fabrication

Unlike a basic weld-in round-to-oval adapter, the 313533 incorporates a V-band connection and includes the weld-on V-band and clamp. This makes it a useful component for custom exhaust builders who want a V-band connection incorporated into their oval exhaust system.

Weld the supplied V-band into the appropriate exhaust location, then use the clamp to secure the connection during installation and service.

Connect to Granatelli's 3" Oval Exhaust System

The 313533 is designed to work as part of a custom oval exhaust system. Pair the adapter with Granatelli 3-inch oval tubing, bends, mufflers and other oval exhaust components to create a system tailored to your vehicle.

The round-to-oval transition is especially useful when starting with an existing 3-inch round exhaust section and transitioning into a lower-profile oval exhaust layout.
