2.5” ID 409 Stainless Steel Exhaust Piping – 45° Mandrel Bend

Build your exhaust system the right way with this 2.5-inch inner diameter 45° mandrel-bent 409 stainless steel exhaust pipe—designed for maximum flow, strength, and longevity.

Crafted from high-quality 409 stainless steel, this bend delivers excellent corrosion resistance and thermal durability while maintaining the flexibility fabricators need for custom exhaust layouts. Unlike mild steel, 409 stainless naturally forms a surface oxide layer that protects against rust-through, making it a favorite among performance builders and OEM manufacturers alike.

Each bend is mandrel-formed to ensure smooth, unrestricted exhaust flow and consistent wall thickness throughout the curve—ideal for performance cars, trucks, and custom applications.

Features:

• 2.5” Inner Diameter (ID) – perfect for high-performance exhaust systems
• Precision 45° mandrel bend for smooth, unrestricted flow
• 409 stainless steel construction for superior strength and heat resistance
• Corrosion-resistant and weld-ready finish
• Ideal for fabricating custom exhaust systems, downpipes, or mid-pipes
