Got an exhaust leak where your manifold, header, or downpipe connects? This graphite gasket ring is here to fix that. It's made from a combo of metal wire mesh and graphite, which gives it a great seal and some serious high-temperature resistance (up to around 550°C / 1022°F). The special ceramic lubricant on the surface helps it seal even better and prevents it from sticking. It's designed to stop those annoying exhaust leaks and reduce vibration transfer, which can cut down on cabin noise. The specific size fits a pipe with an outer diameter of 48mm (about 1.9 inches). The gasket itself has an outer diameter of 64mm (2.5 inches), an inner diameter of 48mm, and is about 17mm (0.7 inches) thick. Just make sure your pipe size matches before you buy! It's a simple, effective replacement part for your car, truck, or motorcycle's exhaust system. One gasket per package.
