Borla Universal Hydroformed Switchfire X-Pipe 3in ID 3in OD Outlets W/O Notches - 60746

The Borla Universal Hydroformed SwitchFire X-Pipe (Part #60746) is a premium custom-exhaust building block designed for enthusiasts and fabricators who demand true Borla engineering in their dual-exhaust setups. Featuring a 3-inch inner-diameter inlet and 3-inch outer-diameter outlets without notches, this universal X-pipe is engineered to be integrated into fully custom exhaust systems — not a direct bolt-on for any single vehicle. If you're building a custom or fabricated Borla exhaust system from scratch, this hydroformed SwitchFire X-pipe is the crossover piece that ties it all together.

Key Features & Benefits

• Hydroformed Construction: Borla's hydroforming process shapes the X-pipe under high internal water pressure, yielding smooth internal contours that promote unrestricted exhaust flow — a clear advantage over traditional stamped or welded crossover designs.
• SwitchFire X-Pipe Design: The SwitchFire crossover configuration is designed specifically to be incorporated into custom dual exhaust systems, giving builders flexibility in routing and layout.
• 3" ID Inlet / 3" OD Outlets (No Notches): The plain, non-notched outlet ends (part #60746) are ideal for fabricators who prefer to make their own custom connections without pre-cut notch profiles — compare to part #60747 which includes notched outlets.
• Reversible Design: The SwitchFire X-pipe series features a reversible design, allowing the unit to be flipped or oriented to suit your specific routing needs during custom exhaust fabrication.
• Universal Fitment: Not vehicle-specific — this piece is purpose-built for custom exhaust fabrication, giving builders maximum freedom to integrate it into virtually any dual-exhaust application that matches the pipe sizing.
• Genuine Borla Quality: Built to the same standards as Borla's full exhaust systems, mufflers, and cat-back kits — the brand known for performance exhaust engineering across muscle cars, trucks, and performance vehicles.
• Not CARB Legal: This product is not CARB legal and is not for sale in California — ideal for track builds, off-road use, or states without CARB emissions requirements.

Frequently Asked Questions

What's the difference between Borla #60746 and #60747?

Both are Universal Hydroformed SwitchFire X-Pipes with a 3" ID inlet and 3" OD outlets. The key difference is outlet style: #60746 (this part) has outlets without notches, while #60747 features notched outlets. Notched outlets are typically used when a specific mating connection profile is required. Choose #60746 if you prefer plain outlet ends for custom welding or slip-fit connections.

Is this a direct bolt-on part for my car?

No. The Borla SwitchFire X-Pipe #60746 is a universal component designed for custom exhaust fabrication. It does not come with vehicle-specific flanges, hangers, or hardware. Proper installation requires fabrication skills and equipment to integrate it into your exhaust system.

Can I use this part in California?

No. This product is not CARB legal and is not for sale in California. It is intended for off-road, track, or non-emissions-regulated use in applicable states. It also carries a Proposition 65 warning.

Does this X-pipe work with Borla mufflers and cat-back systems?

As a universal component, the Borla SwitchFire X-Pipe can be paired with Borla mufflers and exhaust tubing as part of a custom-built system, provided the pipe diameters and routing are compatible. It is not pre-engineered to mate with any specific Borla cat-back kit without custom fabrication.
