3.5 45 Deg Oval Elbow

The BOYCE 3.5 45 Deg Oval Elbow is a precision exhaust or intake piping component designed for custom vehicle builds, turbo installations, and high-performance engine modifications. This 45-degree angled connector allows builders to route ducting, exhaust tubing, or intake piping around engine bay obstacles while maintaining smooth flow dynamics. Whether you're fabricating a complete exhaust system, upgrading intercooler plumbing, or adapting aftermarket supercharger configurations, this elbow provides the directional change needed without requiring custom welding or fabrication work.

Constructed with a 3.5-inch nominal diameter and oval cross-section geometry, this elbow optimizes flow characteristics compared to traditional round ductwork while fitting within tight engine compartment constraints. The 45-degree bend angle allows gradual directional transition, reducing turbulence and backpressure that can compromise boost response or scavenging efficiency. BOYCE components are manufactured to consistent tolerances, ensuring reliable fit with both custom-built piping systems and OEM-compatible aftermarket setups. The oval profile design is particularly effective in intercooler piping applications, where optimized surface area contact improves heat transfer while maintaining structural rigidity under boost pressure.

This component suits engine builders, turbo kit installers, and fabricators working on forced-induction systems where precise piping geometry is critical to performance and reliability. At 3.85 pounds, it's lightweight enough for weight-conscious builds while maintaining the wall thickness required for pressure integrity. Installation compatibility depends on matching your system's diameter specifications and material compatibility; verify your existing piping diameter and confirm all connections use appropriate clamps or welding methods. Mechanics frequently specify BOYCE elbows for domestic muscle car turbo conversions, LS engine swaps, and modern boosted platform upgrades where OEM intercooler piping doesn't accommodate custom routing needs.
