This is the TeamGoNads HPI Baja 5B Buggy Nickel-Coated Race Pipe with the Silencer Tip for use with stock, modified, and big bore engines. The nickel coating on this pipe gives it a nice, durable finish. These will give you great power, a high-performance look, and the sound is awesome too! This is a direct fit on both the RTR and SS versions of the buggy.
