Using your ISR Performance Axle Back Exhaust is straightforward. First, make sure your vehicle is turned off and cooled down. You'll find all the necessary parts in the box, including the muffler section, gasket, bolts, and nuts. Install the muffler section using the provided gasket, bolts, and nuts. Double - check that everything is tightened properly to avoid any leaks. When it comes to maintenance, it's a good idea to check the exhaust system regularly for any signs of damage or loose parts. You can clean the polished parts with a mild stainless - steel cleaner to keep them looking shiny. Avoid using harsh chemicals that could damage the finish. If you notice any strange noises or vibrations while driving, it might be a sign that there's an issue with the exhaust, so have it checked out by a professional.
