What is a mandrel bend and why is it important for exhaust systems?

A mandrel bend is created using a flexible rod (mandrel) inside the tubing during the bending process. This prevents the tube from collapsing or kinking, maintaining its original diameter and shape. For exhaust systems, this ensures smooth airflow and prevents turbulence, which is important for performance and sound.

What makes 304 stainless steel a good choice for exhaust tubing?

304 stainless steel is chosen for exhaust components because it offers excellent resistance to corrosion from moisture and exhaust gases. It also holds up well to the high temperatures found in exhaust systems, making it a durable material for custom fabrication.

What is the center line radius of this bend?

This 45-degree mandrel bend has a 2-inch centerline radius. This measurement is taken from the center of the tube to the center of the bend itself, and it helps determine how much space the bend will occupy.

Product Details

If you're building a custom exhaust system or repairing an existing one, having the right bends on hand makes the job much smoother. This 45-degree mandrel bend from Vibrant is crafted from 304 stainless steel, a material known for its corrosion resistance and durability, making it a solid choice for exhaust work where heat and moisture are constant factors.

This particular bend features a 1.25-inch outer diameter and a 16-gauge wall thickness, offering a good balance between strength and ease of fabrication. The mandrel bending process ensures that the tube maintains its shape and diameter through the bend, which is crucial for smooth exhaust flow and preventing turbulence. This means your engine can breathe more freely, and you avoid creating unnecessary backpressure. It's ready for welding and fabrication with minimal prep work, saving you time in the shop.

This bend is part of Vibrant's extensive line of 304 stainless steel tubing and bends, so you can find other angles and sizes to complete your project. Having a few of these on hand can be a real time-saver when you encounter tight spots or need to route your exhaust system precisely.
