Stainless Works 2 1/8in Rod Builder Exhaust (Slip Fit 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's designed for fabricators who need high-quality components to create a unique exhaust setup for a specific application. This kit gives you the raw materials to bend, cut, and weld exactly what your project requires.

Everything in this kit is made from 304 stainless steel, which is known for its excellent resistance to corrosion, especially important for exhaust components that deal with heat and moisture. The tubing itself is CNC mandrel bent, meaning each bend maintains a consistent diameter and smooth internal radius. This is crucial for optimal exhaust flow, helping to reduce backpressure and improve how efficiently your engine can expel exhaust gases. The tubes measure 2-1/8 inches in diameter with a .065 inch wall thickness, a common size for custom builds that balances strength with workability.

Inside the box, you'll find four 4-foot straight sections of tubing, along with four each of 45-degree, 90-degree, and 180-degree bends. Each piece of tubing has one expanded end, which makes joining sections together easier, especially when using slip-fit connections. Stainless Works proudly manufactures these kits in the USA, and they come with a lifetime warranty, giving you confidence in the materials and construction for your custom project.
