This Flo - Pro exhaust system, part number FLO - 834NM, is a top - notch choice for 2007.5 - 2010 GM vehicles with the LMM 6.6L Duramax engine. It's a 4" downpipe back single exhaust system without a muffler, perfect for race applications. It replaces the restrictive OE exhaust from the downpipe back with a mandrel - bent system. This exhaust comes with all necessary clamps, pre - weld contour bent hangers, and stronger flanges for an easy installation process. You can choose between aluminized steel and stainless steel. It has a single side exit. Not only does it sound amazing, but it also boosts torque, improves mileage, and enhances throttle response. Flo - Pro Exhausts fit all wheelbase and cab configurations unless otherwise specified.

Using this exhaust system is straightforward. First, make sure your vehicle is the right fit (2007.5 - 2010 GM with LMM 6.6L Duramax engine). During installation, use the provided clamps, hangers, and flanges to attach the exhaust to the OE hangers. It's designed for easy mounting, so you should be able to cruise through the process. Since this is a no - muffler exhaust for race applications, be aware that it will be louder than a regular exhaust. When it comes to maintenance, if you choose the aluminized steel option, check for any signs of rust periodically. For the stainless steel option, it's more resistant to corrosion but still clean it regularly to keep it looking good. Also, make sure all the clamps are tight after a few drives to ensure a proper fit and to prevent any rattling.
