Notes
This exhaust system is a great upgrade for your 2020 - 2023 GM vehicle with a 6.6L Duramax engine. To install, first make sure your vehicle has the OEM style 4 - bolt flange off the turbo direct pipe. Then, use the provided clamps, pre - welded contour bent hangers, and stronger flanges to attach the 5" downpipe - back exhaust system. It's designed to be easy to install, so you should be able to get it done without too much hassle. When using your vehicle with this new exhaust, you'll notice better fuel mileage and more torque. For maintenance, periodically check the clamps and flanges to make sure they're tight. If you live in an area with a lot of salt on the roads, you may want to clean the stainless - steel exhaust to prevent corrosion. Keep in mind that this is a no - muffler (straight - pipe) system, so it will have a louder sound than your stock exhaust.
