Using your DC Sports muffler is easy. First, make sure your vehicle is turned off and cooled down. Remove the old muffler carefully according to your vehicle's manual. Then, install the DC Sports muffler in its place, ensuring a proper fit with the 2.5 - inch inlet and outlet. For best results, you may want to have a professional mechanic handle the installation. When it comes to maintenance, regularly check the muffler for any signs of damage or loose connections. Keep it clean by wiping it down with a soft cloth. Avoid using harsh chemicals that could damage the high - gloss finish. If you notice any strange noises or performance issues, it's a good idea to have the muffler inspected right away.
