Using this exhaust system is easy. Since it's a bolt - on system, you can directly install it without any modifications. Just attach the 2.5' reduced section to your factory front pipe or most aftermarket 3' front pipes. When you drive, enjoy the improved performance and the nice exhaust sound. Remember, avoid hitting hard objects with the exhaust system to prevent damage. For maintenance, regularly check the bolts to make sure they are tight. You can clean the stainless steel parts with a mild cleaner to keep it looking good. If you notice any strange noises or issues, have it checked by a professional.
