I purchased this from the official website, but I'm selling it because it wasn't to my liking when I installed it. There may be paint unevenness or dents due to manufacturing. Please consider this as a new/unused item. I am not considering any price reductions. The following is quoted from the official website. Please check the website for more details. RIDERSHOUSE original product. Large-diameter, slash-cut muffler cutter with an outer diameter of 114mm. Inner heat-resistant black painted punching mesh type. High-quality muffler cutter made of high-purity SUS304 stainless steel. The surface is polished to a mirror finish, giving it a very high shine. Inside, a partition plate with 600°C heat-resistant paint is installed at the tip of the original muffler, preventing the original muffler pipe and internal structure from being visible, allowing for a custom look without the aftermarket feel. Designed with a total length of 200mm, the same size as the original muffler cutter. The fixing belt is also hidden behind the muffler cutter after installation, allowing for a clean custom appearance. A drain hole is installed at the bottom to prevent rust caused by water accumulation.
