90 Bend Aluminized 2.5od x 2.5od 5in Radius

The 90 Bend Aluminized 2.5OD x 2.5OD 5in Radius exhaust bend from DYNOMAX is a precision-engineered component designed for custom exhaust system builders and performance-oriented mechanics. This mandrel-bent elbow is essential for routing exhaust piping around engine bays, transmissions, and suspension components where tight-radius transitions are required. Whether you're building a street rod, modifying a truck exhaust system, or creating a custom cat-back setup, this 90-degree bend provides the directional change needed without compromising flow or introducing turbulence.

Constructed from aluminized steel, this exhaust component delivers superior corrosion resistance compared to raw steel, ensuring longevity in both wet climates and high-heat underhood environments. The 5-inch radius on the 90-degree bend minimizes restriction and pressure losses—critical for maintaining backpressure balance and exhaust scavenging efficiency. Mandrel bending (the manufacturing process that creates smooth, uniform wall thickness throughout the bend) preserves internal diameter consistency, preventing the pinching that occurs with pressed or welded elbows. The 2.5-inch outer diameter accommodates standard 2.5-inch mandrel-bent piping, making it compatible with most modern performance exhaust systems and aftermarket tubing stacks.

This bend suits builders constructing custom exhaust systems, transmission tunnel modifications, and engine bay reconfiguration projects on street vehicles, race cars, and off-road trucks. Its compact footprint (18.4 inches in length, 2.86 pounds) makes it easy to position during welding and assembly, and the aluminized coating accepts TIG or MIG welding without surface prep. Installation requires basic exhaust fabrication skills—clamping, aligning, and tacking before final welding. Pair this component with quality mandrel-bent straight pipe, mufflers, and hangers to achieve a professional-quality exhaust system that flows efficiently and resists rust for years.
