X AUTOHAUX 5" SS304 Mandrel 90° Exhaust Elbow Pair — 5in OD, 1.5mm Wall, Rolled Bead Ends

A pair of 5-inch SS304 stainless-steel 90° mandrel-bend elbow pipes designed for reliable, weldable connections in custom and modified car exhaust systems.

These X AUTOHAUX elbow pipes give you a robust, ready-to-fit elbow section for routing and joining 5" exhaust tubing. Built from SS304 stainless steel with a mandrel bend profile and rolled bead ends, the elbows are intended for cutting, splicing, or welding into aftermarket exhaust assemblies. Each elbow measures approximately 18 x 18 cm (7.09" x 7.09") with a 127 mm (5") outer diameter and a 1.5 mm wall thickness, making them suitable for a wide variety of performance and custom fabrications.

How will these elbows fit into my custom exhaust layout?

These elbows are universal 90° mandrel bends sized to match 5" (127 mm) outer-diameter tubing, so they can be used wherever a right-angle transition is needed. The rolled humps at both ends help with clamp placement and stabilization during installation, and the straight back arc length gives room for trim or length adjustments.

• Outer diameter: 127 mm / 5" to match 5" exhaust pipes
• Back arc length: 280 mm / 11.02" for routing allowance
• Wall thickness: 1.5 mm / 0.06" for structural integrity
• Ends include humps for easier clamping or welding

Are these elbows durable enough for high-heat exhaust use?

Manufactured from SS304 stainless steel, the elbows offer good corrosion resistance and thermal stability for typical automotive exhaust temperatures. While SS304 is commonly used for aftermarket exhaust components, final durability will depend on installation quality and operating conditions.

• Material: SS304 stainless steel resists corrosion and oxidation
• Mandrel bend maintains internal diameter for better flow
• 1.5 mm wall thickness balances weight and strength
• Suitable for welding, cutting, or clamping during fabrication

How do I install and secure these 90° elbow pipes?

They are designed for flexible installation—use clamps for removable joins or weld the seams for permanent connections. Before final assembly, dry-fit and measure to ensure proper alignment; trimming the ends or adding short straight adapters may be required for a flush, leak-free join.

• Dry-fit first to confirm routing and clearances
• Use T-bolt or V-band clamps on the rolled humps for secure clamp joins
• Weld joints for permanent, leak-resistant installations
• Allow 1–5 mm tolerance for manual measurement variations

What should I check before ordering these elbows?

Verify your exhaust tubing outer diameter is 5" (127 mm) and confirm the required bend direction and back arc length will clear suspension, chassis, and bodywork. Because these elbows are universal, careful measurement prevents fitment issues and reduces on-vehicle trimming and rework.

• Confirm pipe OD is 127 mm / 5" for compatibility
• Measure available space against the 280 mm back arc length
• Plan for clamps or welds and any adapters needed
• Note: product sold as two pieces per package

Who is this for? This pair of X AUTOHAUX 5" SS304 90° mandrel-bend elbows is intended for DIY fabricators, custom exhaust shops, and car enthusiasts modifying or repairing 5" exhaust systems. If you need durable, weldable elbow sections to route exhaust gases, adapt existing piping, or create a bespoke muffler/pipe layout, these elbows provide a practical, universal solution. Be sure to measure your system and plan clamp or weld locations before installation.
