Using this exhaust tip is easy. First, make sure your vehicle's exhaust system is turned off and cooled down. Then, align the 2.875 - inch inlet of the tip with your existing exhaust pipe and bolt it on tightly. When it comes to maintenance, regularly clean the tip with a mild soap and water solution to keep it looking shiny. Avoid using harsh chemicals as they may damage the stainless - steel finish. Also, check the bolts periodically to ensure they are still tight. If you notice any signs of rust or damage, it's best to replace the tip to keep your exhaust system in good condition.
