304 Stainless Bent Elbow 1.625 90-Degree

The 304 Stainless Bent Elbow 1.625 90-Degree from Woolf Aircraft Products is a precision exhaust manifold component engineered for marine engines, water-cooled inboards, and stern-drive applications where durability and reliability matter. After years on the water, any experienced boater knows that corrosion and exhaust system failures can derail a season—this 90-degree elbow eliminates those risks with marine-grade 304 stainless construction that resists saltwater and freshwater corrosion alike.

This bent elbow features a 1.625-inch inside diameter with a 2.5-inch bend radius, designed to optimize exhaust gas flow while maintaining structural integrity under sustained engine heat and pressure cycles. The 16-gauge 304 stainless steel wall provides excellent fatigue resistance and prevents warping, cracking, or separation—critical factors in high-vibration marine environments where substandard materials fail quickly. The smooth, welded construction minimizes turbulence and supports efficient engine breathing, contributing to consistent performance and fuel efficiency across a wide RPM range.

Boaters restoring classic inboards, upgrading aging exhaust systems, or building custom marine power plants will find this component ideal for 1.625-inch exhaust piping configurations. Installation requires standard welding or clamp connections, and the 90-degree angle accommodates tight engine compartment layouts common on cruisers, day boats, and performance runabouts. Whether you're replacing corroded factory elbows or fabricating a complete exhaust system, this Woolf Aircraft Products elbow delivers the durability and precision fit that keeps your engine running clean and your boat running strong for years to come.
