A-KARCK Exhaust 45° Tube 3.5" OD mandrel bend pipe 🚗
Description:
This 45 degree mandrel-bent exhaust tube with a 3.5 inch outer diameter helps you build or repair a custom exhaust system with smoother airflow and easier fitment. It is a stainless steel elbow with flared ends for slide-in assembly, intended to improve exhaust flow and simplify welding and joining when fabricating pipes for cars or performance projects.
Key Points
The mandrel bend keeps the internal diameter consistent through the curve, which helps reduce turbulence and preserve flow. The pipe includes an expanded end to allow a snug slip-fit connection with other sections, making alignment and welding more straightforward. Made from stainless steel, the tube resists corrosion better than mild steel, according to the manufacturer, and is supplied at a length suitable for trimming and fitting to custom layouts.
Technical Specifications
- Name: A-KARCK 45 Degree Tube 3.5" OD
- Outer Diameter: 3.5 inches
- Bend Angle: 45 degrees
- Material: Stainless steel
- End Type: Expanded/flared slip-fit ends
Usage Recommendations
Measure the existing exhaust routing and allow extra length for trimming and tacking before completing final welds. The flared end simplifies sliding sections together, but cutting and welding are required to finish the joints and ensure a leak-free system. For best results, tack-weld first, verify fit and clearances around suspension components, and then complete full welds to avoid distortion.
Practical Tips
Consider that this tube is meant for custom fabrication and may not match factory-fit parts exactly. If corrosion or damage affects surrounding sections, replacing adjoining pieces and checking hangers and clamps will improve longevity. Welding stainless steel properly and using compatible filler material helps maintain corrosion resistance and appearance.
