Product Information

Full details

The Jetex 3.5-inch 90-degree exhaust bend is designed for automotive enthusiasts and fabricators looking for professional-grade exhaust components for custom builds, kit cars, and high-performance exhaust systems. These mandrel-bent components ensure optimal exhaust gas flow, though users should note that welding and custom cutting are required for final installation, making them best suited for those with fabrication experience.

Extended Product Information

FAQs

Are these bends suitable for stainless steel exhaust systems?

This specific item is designed for general exhaust fabrication. Ensure you select the matching material grade (Stainless or Mild Steel) to ensure proper weld compatibility.

Can I use these for a turbo-manifold build?

Yes, their durable construction makes them ideal for high-heat applications, though thickness should be verified against your specific pressure requirements.

Do I need to clamp the slotted end?

While the slot makes it easier to fit, it is recommended to weld the joint for a permanent, exhaust-gas-tight seal in automotive applications.

Is the 3.5-inch measurement the internal or external diameter?

Jetex exhaust tubing measurements generally refer to the outer diameter (OD) of the pipe.

Can these be trimmed to a different angle?

Yes, because they are high-quality steel, they can be cut and shortened to achieve an angle of less than 90 degrees if required.

Troubleshooting

Joint leak after installation

Ensure the weld bead is continuous and the slot on the flared end is fully covered by the joining pipe or weld material.

Difficulty sliding onto existing pipe

Check if the mating pipe has any burrs or deformities; file the edge of the mating pipe until it fits smoothly into the flared section.

Pros and Cons

Pros

  • Superior mandrel-bent design prevents tube collapse or restriction
  • Flared and slotted design simplifies alignment and connection
  • High material durability for long-term heat resistance
  • Perfect for complex custom exhaust routing

Cons

  • Requires professional welding equipment and fabrication skills
  • Not intended for direct "bolt-on" vehicle-specific upgrades
  • Material choice requires proper surface preparation prior to welding

Setup, Compatibility & Care

To install the Jetex 3.5-inch bend, first measure your existing exhaust path and cut the tubing to the required length using a metal bandsaw or reciprocating saw. Clean the joining edges thoroughly to remove burrs or debris. Slide the flared/slotted end onto the connecting pipe and use an exhaust clamp for initial positioning. Once the fitment is confirmed, proceed to TIG or MIG weld the seam. To ensure long-term performance, apply a high-temperature exhaust coating or paint to the weld area to prevent oxidation and rust.
