304 Stainless Bent Elbow 4.000 90-Degree

The 304 Stainless Bent Elbow 4.000 90-Degree from Woolf Aircraft Products is a precision-engineered exhaust or intake piping component designed for high-performance automotive and motorsport applications. This mandrel-bent elbow serves as a critical junction fitting in custom exhaust systems, turbo intake manifolds, and engine bay plumbing where directional changes are required without flow restriction. Whether you're building a competition engine or upgrading a street machine, this 90-degree elbow maintains consistent bore diameter throughout the bend for optimal flow characteristics.

Constructed from 304 stainless steel, this bent elbow resists corrosion, heat cycling, and the caustic byproducts of combustion—making it ideal for both street and track applications where longevity matters. The 4.000-inch bore diameter accommodates large-displacement engines and high-volume airflow requirements common in turbocharged, supercharged, and naturally aspirated performance builds. The 90-degree mandrel-bent design eliminates turbulence-inducing creases and maintains smooth inner geometry, preserving horsepower and reducing exhaust scavenging losses.

This fitting is perfect for fabricators, engine builders, and automotive enthusiasts looking to construct high-performance exhaust systems. Its design ensures compatibility with various applications, making it a versatile choice for anyone involved in custom automotive work. With its robust construction and optimal flow characteristics, this elbow is a reliable component for enhancing engine performance.
