Using this DC Sports axleback exhaust is easy. First, make sure your car is on a flat and stable surface. Then, simply remove the old exhaust and bolt on the new one using the included hardware and gaskets. There's no need for any modifications. For normal driving, you'll enjoy the enhanced sound right away. When it comes to maintenance, regularly check the connections to ensure they are tight. If you notice any signs of rust or damage, clean the exhaust with a mild soap and water solution and dry it thoroughly. Avoid using abrasive cleaners as they can damage the finish. In extreme weather conditions, especially in areas with a lot of salt on the roads, rinse the exhaust more frequently to prevent corrosion. And always remember, this is a reversible system, so if you ever need to go back to the original exhaust, it's easy to do.
