Mild steel mandrel bends
Patriot's mild steel mandrel bent exhaust pipes are available in many combinations of radius, tube diameter and length to suit professional header builders, custom muffler shops and do-it-yourselfers alike.

Stainless steel mandrel bends
Patriot's new 304 stainless steel mandrel bends combine excellent physical properties with a remarkable resistance to corrosive agents found in automotive exhaust emissions. 304 material is the most cost-effective grade of nonmagnetic stainless steel for high strength racing applications or custom street machine exhaust systems.

Aluminized mandrel bends
Aluminized tubing has become increasingly popular in exhaust system fabrication as a lower cost alternative to stainless steel. Patriot offer a complete assortment of bends in all the popular exhaust system sizes.
