Using this FLO 823 exhaust system is easy. First, gather all the parts that come in the kit, like the clamps, hangers, and flanges. Then, remove the old restrictive OE components from your 2001 - 2005 GM truck with the 6.6L Duramax. Use the existing OE hangers to install the new 4' aluminized exhaust system with the high - flow muffler. Make sure to tighten all the bolts and clamps properly. When it comes to maintenance, regularly check the clamps and bolts to ensure they are tight. If you chose the aluminized steel option, keep an eye out for any signs of rust. If you have the stainless steel option, it will be more resistant to corrosion. Also, remember that this system uses the OEM Cat for emissions, so don't tamper with it to avoid any legal issues.
