45 Degree Brushed Mandre l Bend 4.00in O.D.

The 45 Degree Brushed Mandrel Bend 4.00in O.D. from VIBRANT PERFORMANCE is a precision exhaust component engineered for builders and technicians who demand smooth airflow transitions in custom exhaust systems. This mandrel-bent elbow serves as a critical junction point in high-performance and street applications where exhaust gas velocity and minimal turbulence directly impact engine efficiency and power output. Whether you're fabricating a complete exhaust system or replacing a damaged section, this 45-degree bend ensures optimal routing while maintaining structural integrity under thermal stress.

Constructed from durable stainless steel with a brushed finish, the 45 Degree Brushed Mandrel Bend features a 4-inch outer diameter and a 4-inch bend radius, which minimizes flow restriction and maintains consistent tube wall thickness throughout the curve. The mandrel-bending process—a hallmark of VIBRANT PERFORMANCE's manufacturing—prevents collapse and rippling that occurs with conventional bending methods, preserving internal cross-sectional area and reducing backpressure. At 0.83 lbs, this component is lightweight yet robust, with 1.66-inch leg extensions on each side providing ample material for secure clamping, welding, or coupling to adjacent pipe sections.

This mandrel bend is ideal for exhaust system fabrication on turbocharged and naturally aspirated applications where thermal cycling and vibration demand corrosion-resistant, precision-engineered components. Installers benefit from the stainless steel construction, which withstands high exhaust temperatures and extends system service life. The brushed finish resists oxidation discoloration while maintaining a professional appearance, making it suitable for both visible undercarriage applications and engine bay installations. Proper fitment requires confirmation that your system uses 4-inch O.D. tubing; the 4-inch radius allows integration into tight chassis layouts without excessive space demands.
