Product Description
Build cleaner, tighter exhaust runs with the DIAMOND EYE 524526 3" 45° stainless elbow. CNC mandrel-bent T409 stainless keeps flow smooth and backpressure low, while the 45-degree geometry helps you clear frames, tanks, and crossmembers on custom diesel systems. One end is expanded to simplify slip-fit assembly and clamping for a leak-resistant install.
Fitment
- Universal 3-inch exhaust systems (diesel & gas) – ideal for custom turbo-back, cat-back, stack, and repair work.
- Material: T409 stainless steel, mandrel bent.
- Bend angle: 45 degrees. End style: one end flared/expanded for easier joining.
- Use with: 3" tubing, 3" band or U-bolt clamps, reducers/adapters as needed.

FAQ
Is the 524526 elbow truly universal?
Yes. It’s a universal 3" 45° elbow for custom builds and repairs across diesel and gas platforms. Verify clearance and downstream routing on your specific chassis.
What stainless grade is used?
T409 stainless steel—great corrosion resistance and durability for year-round trucks.
Does one end come flared for easier assembly?
Yes. One end is expanded to simplify slip-fit and clamping in most configurations.
Will this elbow neck down the flow?
No. It’s CNC mandrel-bent for smooth, free-flowing radius with minimal turbulence.
What clamps should I use?
Use 3" stainless band clamps for best sealing. U-bolt clamps can work but may mark tubing.
