Exceeding industry standards with powerful performance and great quality, and making 50-state legal 2007-2013 intake components and 2014-2017 exhaust parts stand as the core principles of SLP’s business, now enjoying over 40 years of success. Always seeking new ways to improve their products, including those for your Silverado, SLP’s focus is on making components that generate real-world, practical power gains while remaining fully street legal – in fact, SLP means “Street Legal Performance.” Stainless steel builds and mandrel-bent tubing appear throughout their PowerFlo and Loudmouth 2009-2013 cat-back exhaust systems and their 2014-2017 cat-backs. The company doesn’t ignore the other end of the air system, either, with high quality 2009-2017 supercharger kits & accessories, plus a range of high-flowing 2007-2017 cold air intakes to boost engine aspiration and power. They even make 2014-2017 tuners – and all these parts can be found on American Trucks.
