Building a custom exhaust or intercooler setup? This 5-inch diameter straight pipe is made from T304 stainless steel—the good stuff—and comes in a 4-foot (48-inch) length. It’s mandrel-bent for smooth, consistent flow without kinks or weak spots. The polished finish looks clean whether you’re running it exposed or wrapping it. Perfect for DIY projects where you need to fab your own system for a car, truck, or performance build. Use it for exhaust routing, intercooler piping, or any other high-flow application. Since it’s straight, you can cut it, weld it, or clamp it to fit your needs. No cheap materials here; just a solid, versatile pipe that handles heat and pressure like a champ.
