What is a 'pie cut' in exhaust fabrication?

A pie cut is a section of tubing that has been cut at an angle, like a slice of pie. When multiple pie cuts are welded together, they allow you to form a smooth, curved pipe section with a tighter radius than you could achieve with a single piece of bent tubing.

What does '1D bend' mean?

A 1D bend refers to the radius of the bend. In this case, a 1D bend means the radius of the curve is equal to the diameter of the tubing, which is 4 inches for this kit. This results in a fairly tight bend.

What material are these pie cuts made from?

These pie cuts are made from stainless steel, which is a popular choice for exhaust components because it holds up well to high temperatures and resists rust and corrosion.

Product Details

If you're building a custom exhaust system, especially one that needs tight bends or a unique look, these pie cuts from Stainless Works can be a real help. This kit gives you ten 4-inch diameter pieces of 1D (1.5" radius) mandrel-bent tubing, cut into sections. You can then weld these sections together to form smooth, precise curves that are tough to achieve with a single piece of tubing.

These are made from stainless steel, which is a solid choice for exhaust work because it holds up well to heat and resists corrosion. The 1D bend means the radius of the bend is equal to the diameter of the tubing, giving you a fairly tight curve that's useful for routing exhaust in tight spaces. You'll need to be comfortable with welding to use these effectively, as you'll be joining multiple pieces to create your final pipe section.
