Description

AEROFLOW 304 Stainless Steel Full Donut, 1.75″, 1-3/4″, 44mm

Engineered for professional fabricators and custom exhaust builders, the Aeroflow 3″ 304 Stainless Steel Full Donut (AF9511-1750) provides the ultimate flexibility when routing complex exhaust systems, turbo manifolds, and custom intake pipework.

Manufactured from high-grade 304 stainless steel, this full donut offers exceptional corrosion resistance, high-temperature durability, and a clean mill finish that is ready for TIG welding and polishing. The uniform wall thickness ensures smooth, unrestrictive exhaust gas flow around tight radiuses and custom pie cuts without collapsing or thinning dangerously under fabrication.

Whether you are building a custom race exhaust, a downpipe, or intricate mandrel-bent pipe routing, cutting sections from a full donut allows you to achieve tight-radius bends and compound angles that standard mandrel bends simply cannot reach.

Key Features:

• Premium 304 Stainless Steel Construction: Delivers superior heat resistance, long-lasting durability, and excellent corrosion protection under harsh track and road conditions.

• Versatile Fabrication Potential: Ideal for cutting custom pie-cuts, tight-radius bends, and intricate transition sections for custom exhaust and turbo systems.

• Precision Wall Thickness: Ensures consistent structural integrity and makes clean, professional TIG welding straightforward.

• High quality, contaminant-free stainless: Produces clean weld beads, for a show quality welding job!

• Polishes Up Clean: Can be linished, brushed, or mirror-polished to suit your engine bay or under-car aesthetics.
