What are pie cuts used for in exhaust fabrication?

Pie cuts are sections of tubing that have been cut at an angle. When welded together, they form a bend in the exhaust pipe. This allows fabricators to create custom curves and shapes that wouldn't be possible with a single piece of straight tubing.

What does '1D/1.38in' radius mean?

The '1D' refers to the diameter of the tubing, meaning the center of the bend follows the tube's own diameter. The '1.38in' specifies the actual measurement of that radius. A tight radius like this allows for sharper, more compact bends in your exhaust system.

What is the gauge of the steel used for these pie cuts?

These pie cut pieces are made from 16-gauge steel. This gauge offers a good balance, being strong enough for exhaust applications while still being manageable for welding and shaping during fabrication.

About this part

Product Details

This pack gives you five Stainless Bros pie cut pieces, each measuring 1-3/8 inches in diameter with a 1D/1.38 inch tight radius. They are made from 16-gauge steel, perfect for fabricating custom exhaust bends where precise curvature is needed.

These pie cuts allow you to build complex exhaust routing by welding the individual sections together. The tight radius means you can achieve sharper bends than with standard tubing, giving you more flexibility in tight engine bays or when routing exhaust systems for specific performance or aesthetic goals. The 16-gauge steel offers a good balance of strength and workability for welding and shaping.
