304 Stainless Bent Elbow 3.500 90-Degree

The 304 Stainless Bent Elbow 3.500 90-Degree from WOOLF AIRCRAFT PRODUCTS is a precision exhaust bend engineered for custom automotive exhaust systems, turbo installations, and high-performance engine builds. Whether you're fabricating a header, routing exhaust around tight engine bay constraints, or designing a complete custom exhaust manifold, this 3.5-inch diameter bend provides the tight radius control needed to maintain optimal flow dynamics while fitting modern and classic vehicles alike. Mechanics and fabricators rely on aircraft-grade stainless bends to eliminate kinks, maintain structural integrity under heat cycling, and ensure repeatable quality across multiple builds.

Manufactured from 304 stainless steel, this bent elbow features a 3.5-inch centerline radius and a true 90-degree bend angle, critical specifications for turbo manifold routing and custom header applications where precise geometry directly affects scavenging efficiency and thermal management. The 16-gauge wall thickness delivers excellent strength-to-weight ratio without excessive material bulk, while the smooth interior radius minimizes exhaust gas turbulence and promotes laminar flow. Stainless construction resists oxidation, corrosion, and thermal fatigue far better than mild steel alternatives, extending component life in high-temperature exhaust environments where temperatures regularly exceed 1,200 degrees Fahrenheit.

This component suits fabricators, engine builders, and automotive enthusiasts constructing custom exhausts for turbocharged engines, LS swaps, and performance street applications. The 3.5-inch diameter accommodates mid-sized turbos and header primary tubes common in modified four-cylinder and V8 applications. Installation requires TIG welding for optimal strength and leak prevention; professional tube notching and welding techniques ensure proper fitment and durability. Pair this bend with matching diameter piping, flanges, and collectors to complete a cohesive exhaust system that balances flow capacity with spatial constraints.
