Using this exhaust tip is a breeze. Just slide it onto the exhaust of your 2015 - 2025 GMC or Chevrolet truck with a 6.6L Duramax engine. It's designed to fit snugly. When installing, make sure it's properly aligned for a perfect look. As for maintenance, clean it regularly with a mild soap and water solution to keep its shine, whether it's the polished or black finish. Avoid using abrasive cleaners that could scratch the stainless steel. Also, check the fit periodically to ensure it hasn't loosened over time.
