Using this exhaust system is straightforward. First, make sure your truck is a 2007.5 - 2010 GM with an LMM 6.6L Duramax engine, as it won't fit cab and chasis trucks. For installation, it's a bolt - on process with no welding required. You'll find all the necessary clamps and parts in one box, and they're designed to fit directly onto the OEM hangers. It should take about one and a half to two hours to install. Once installed, you'll notice an increase in horsepower, torque, and fuel efficiency, along with a better - sounding exhaust. As for maintenance, check the exhaust regularly for any signs of damage or rust. The fully sealed tubing helps prevent rust, but it's still a good idea to keep an eye on it. If you have any issues, the product comes with a 1 - year warranty, so you can get in touch with the manufacturer for support.
