If you're diving into some exhaust work, let me tell you about this ATP Turbo Weld Bung. It's made from 304 stainless steel, which means it’s not just tough but also resistant to rust and corrosion. This is the kind of stuff you want when you're working on your ride. The 18mm size is spot-on for fitting an O2 sensor, and the coped/radiused design makes it a breeze to weld onto your exhaust pipe.
Now, if you’re running a 3-inch pipe, this bung fits perfectly. But don’t sweat it if your setup is a bit different—it's versatile enough to work with pipes ranging from 2 inches to 4 inches. Trust me, that radius is way better than a flat fitting. It helps with the flow and makes for a cleaner installation. Plus, it saves you the hassle of having to trim or modify too much.
Whether you're upgrading your exhaust or just replacing a worn-out part, this weld bung is a solid choice. It’s all about making your setup smoother and more efficient, and you can’t go wrong with that.
