Stainless Works 3in Rod Builder Exhaust (Butt Weld Kit)

If you're building a custom exhaust system from scratch, this Rod Builder Exhaust Kit from Stainless Works is a solid starting point. It gives you the raw materials to fabricate exactly what you need for your project, whether it's for a classic car, a custom build, or a performance application. This kit is designed for fabricators who want to create a unique exhaust path with precise bends and smooth flow.

What sets this kit apart is the material and the manufacturing. You get CNC mandrel-bent tubing made from 304 stainless steel, which is known for its excellent corrosion resistance, especially important for exhaust components. The 3-inch diameter with a .049 wall thickness is a common size for performance builds, and the mandrel bends ensure that the tubing maintains its diameter through the curves, promoting optimal airflow. This kit includes four 4-foot straight sections, four 45-degree bends, four 90-degree bends, and four 180-degree bends, giving you a lot of flexibility in your design. Remember, these are butt weld pieces, meaning you'll need to join them using your preferred welding method, and they don't have expanded ends, so you'll need to plan your connections accordingly. We recommend using 308L SS welding rod for joining this stainless steel.

This kit is proudly made in the USA and comes with a lifetime warranty. It's a versatile option for anyone looking to craft a custom exhaust system with high-quality materials. Keep in mind that this kit is not CARB approved and cannot be shipped to California.
