X AUTOHAUX 5" SS304 Mandrel-Bent 90° Exhaust Elbow Pair — 5" OD, 1.5mm Wall, Weld-Ready

These stainless-steel elbow tubes are made to join 5-inch exhaust piping at a true 90-degree angle while keeping the interior contour smooth for improved flow. Constructed from SS304 and finished for fabrication, the pair includes rolled ends to accept clamps or allow welding, making them a versatile choice for DIY fabricators, performance shops, or anyone modifying an exhaust layout.

How do these elbows fit into a custom exhaust build?

The elbows act as transition pieces where a system needs a compact 90° direction change without excessive internal distortion. Their mandrel bend maintains a consistent inner diameter, reducing turbulence and simplifying alignment during installation. Each pipe features formed bead edges to stabilize clamps and help seat the join.

• Outer diameter: 127 mm (5") to pair with 5" piping and clamps
• Back arc length: 280 mm (11.02") for predictable routing and overlap
• Wall thickness: 1.5 mm for structural resistance and weldability
• Humped ends for secure clamp seating or tack-weld points

What materials and finishes are used, and why does it matter?

The elbows are stamped from SS304 stainless steel, chosen for its corrosion resistance and heat tolerance in exhaust environments. The surface is prepared to accept cutting, splicing, welding, or polishing, so it integrates easily with fabricated systems. This balance of durability and workability makes them suitable for street and many performance applications.

• SS304 construction resists oxidation and road corrosion
• Smooth mandrel bend preserves internal flow characteristics
• Prepared ends accelerate welding or allow clamp installation
• Finished exterior reduces prep time for painting or coating

How do I measure and confirm compatibility before buying?

Measure your existing pipe OD and available clearance where the 90° turn must occur. These elbows are built to a 5" outer diameter; confirm that your clamps, connectors, or adjoining pipes match that size. Allow for the 280 mm back arc and the 7.09" overall leg lengths when checking fitting room behind bumpers, brackets, or heat shields.

• Confirm outer diameter: 127 mm / 5" to match mating parts
• Check back arc length: 280 mm for routing and fitment space
• Account for wall thickness of 1.5 mm when planning welds
• Expect 1–5 mm variance due to manual measurement tolerances

What installation options and tools will I need?

These elbows are designed for flexible installation methods: clamp-on with the humped ends for secure seating, or welded for a permanent join. Basic fabrication tools like a tubing clamp, exhaust band clamps, a TIG/MIG welder, angle grinder, and measuring tools are typical requirements. Use proper exhaust hangers and heat management to avoid stress at the joint.

• Clamp installation uses the raised bead for reliable fit
• Welding offers a permanent, leak-resistant connection
• Common tools: band clamps, welder, grinder, measuring tape
• Consider heat shielding or hangers for long-term durability

Who is this for: These X AUTOHAUX SS304 90° mandrel elbows are aimed at vehicle owners, fabricators, and tuners who need a high-quality, work-ready 5" elbow for custom exhaust routing or repairs. If you build or modify exhaust systems, require corrosion resistance, and prefer pieces that are simple to clamp or weld, this two-piece set offers practical value and consistent fitment. Always verify dimensions against your system before purchase to ensure proper integration.
