2.5” ID 409 Stainless Steel Exhaust Piping – 10’ Straight

Engineered for performance, durability, and precision fitment, this 2.5-inch inner diameter 409 stainless steel exhaust piping is the perfect foundation for your custom exhaust system or high-performance build.

Constructed from 409-grade stainless steel, this tubing offers superior corrosion resistance compared to mild steel while maintaining the strength and heat tolerance needed for demanding exhaust environments. Unlike 304 stainless, 409 stainless develops a protective surface oxidation layer that resists rust-through, making it ideal for long-term use in real-world driving conditions.

Each 10-foot straight section is mandrel-bent ready, allowing for unrestricted exhaust flow and smooth transitions when fabricating headers, mid-pipes, or full custom exhaust setups.

Features:

• 2.5” Inner Diameter (ID) – ideal for high-flow exhaust systems
• 10-foot straight section for maximum fabrication flexibility
• Made from high-quality 409 stainless steel
• Excellent heat resistance and structural strength
• Corrosion-resistant and weld-friendly
• Perfect for custom exhaust builds, race applications, or replacements
