Using your ISR Performance Series II EP Single exhaust is straightforward. First, make sure you have all the parts in the box: the rear section, non - resonated mid - section, and the gasket and hardware pack. Follow the installation instructions carefully. When installing, ensure all connections are tight to prevent any leaks. Remember, this product is designed for off - road use only, so don't use it on public roads. For maintenance, regularly check the exhaust for any signs of damage or loose parts. You can clean the stainless - steel surface with a mild cleaner to keep it looking good. If you want to change the mid - section or rear section later, the modular design makes it easy to swap them out according to your needs.
