45 Degree Brushed Mandre l Bend 3.50in O.D.

The 45 Degree Brushed Mandrel Bend 3.50in O.D. from Vibrant Performance is an essential component for fabricators and performance enthusiasts building custom exhaust systems, intake manifolds, and turbo piping. Mandrel bends are engineered to maintain consistent internal diameter throughout the bend, preventing collapse and flow restriction that plague cheaper compression-bent alternatives. This 45-degree configuration allows precise directional routing in tight engine bays, making it ideal for custom headers, cold-air intakes, and turbocharger discharge pipes where space constraints demand precision bends without kinks or material thinning.

Vibrant Performance's brushed finish delivers both aesthetic appeal and practical corrosion resistance, particularly important for underhood applications exposed to heat cycles and moisture. The mandrel bending process ensures the 3.50-inch outer diameter tubing maintains structural integrity and flow characteristics throughout the curve—critical for maximizing volumetric efficiency in performance builds. The lightweight 0.64 lb construction makes this bend easy to handle during installation while remaining rigid enough to support system loads without sagging or vibration-induced fatigue. This MPN 13334 bend is precision-manufactured to OEM specifications, ensuring reliable fitment in both bolt-on upgrade kits and full custom fabrication projects.

Mechanics, fabricators, and weekend builders working on turbocharged, supercharged, or naturally aspirated engine builds benefit from having quality mandrel bends in stock for exhaust and intake manifold construction. The 45-degree angle accommodates common routing scenarios found in engine bay layouts across domestic and import platforms, from LS-powered builds to modern turbo four-cylinders. Installation requires basic TIG welding skills and proper tube preparation; flanging or coupling adapters are typically added to connect this bend to flanged manifold outlets or downstream piping. For maximum flow and reliability in street or competition applications, pair this bend with matching tubing diameter and quality welded construction practices.
