Stainless Works 3 1/2in Rod Builder Exhaust (Butt Weld Kit)

This Rod Builder Exhaust Kit from Stainless Works gives you the raw materials to start fabricating your own custom exhaust system. You'll receive four 4-foot sections of straight 3-1/2 inch diameter tubing, along with four each of 45-degree, 90-degree, and 180-degree bends. All the tubing in this kit is made from 304 stainless steel, which is known for its strong resistance to corrosion, and features a .065 inch wall thickness. The bends are CNC mandrel bent, meaning they maintain their diameter throughout the curve for optimal exhaust flow.

This kit is designed for custom fabrication projects where you need to build an exhaust system from scratch. Since it's a butt weld kit, none of the tubes have expanded ends, so you'll need to plan your connections accordingly. The 304 stainless steel construction makes this a durable option for a wide range of applications, and it's proudly made in the USA. For welding, Stainless Works recommends using 308L SS welding rod.

If you're building a unique exhaust system for a project car, hot rod, or custom build, this kit provides the essential components. Remember that this kit is universal and intended for custom fabrication; you'll need to cut, fit, and weld the pieces to your specific application. It's not CARB approved and cannot be shipped to California.
