Using this exhaust system is a breeze. First, find a safe and flat place to work on your 2001 - 2007 Duramax truck. The kit comes with all the parts you need, like clamps and hangers. Just mount it to the existing OE hangers. Connect the pieces following the instructions that come with the kit. Make sure all the connections are tight. When it comes to using the exhaust, it's designed for track applications. So, use it on the race track to get the most out of it. As for maintenance, regularly check the clamps to make sure they're not loose. If you chose the aluminized steel option, it might rust over time, so you can give it a protective coating. The stainless - steel option is more resistant to rust but still needs a look - over now and then. Keep an eye on the exhaust for any signs of damage or wear, and you'll enjoy the great sound and performance for a long time.
