What materials are included in the Stainless Works Rod Builder Exhaust Kit?

The kit includes four 4-foot straight tubes, four 45-degree bends, four 90-degree bends, and four 180-degree bends. All components are made from 304 stainless steel with a .049 wall thickness.

What is the benefit of CNC mandrel bent tubing?

CNC mandrel bending ensures that the tubing maintains a consistent diameter throughout the bend. This prevents kinks and restrictions, which helps maintain smooth airflow for improved exhaust system performance.

Do I need any special welding rod for this kit?

Yes, Stainless Works recommends using 308L SS welding rod for fabricating your custom exhaust system with this kit. This type of rod is suitable for welding 304 stainless steel.

Product Details

Stainless Works is known for making well-built exhaust components, and this Rod Builder Exhaust Kit is no exception. If you're fabricating a custom exhaust system, this kit gives you the foundational pieces to get started. It's designed to help you achieve optimal flow through your bends, which is key for any performance exhaust build.

Everything in this kit is made from 304 stainless steel, chosen for its strong resistance to corrosion, so your custom exhaust will hold up over time. The tubing measures 2 1/2 inches in diameter with a .049 wall thickness, and all the bends are CNC mandrel bent. This process ensures consistent diameter throughout the bend, preventing kinks and maintaining smooth airflow. You get four 4-foot straight tubes, plus four each of 45-degree, 90-degree, and 180-degree bends. Keep in mind that the ends are not expanded, so you'll need to plan your connections accordingly. For welding, we recommend using 308L SS welding rod.

This kit is proudly made in the USA and is a solid option for anyone looking to build a custom exhaust system from scratch. You'll need to source additional materials and perform the welding yourself, but this kit provides the high-quality tubing and bends to get you going.
