SLP’s mission is revealed by its very name – which stands for “Street Legal Performance” – in building performance parts that are 50-state legal, even in California, and including 2007-2017 intakes, 2007-2017 exhaust components, and the like for use on Sierra pickups. SLP’s exhaust products include 2007-2013 and 2014-2017 cat-back exhaust systems that are made from rust-defying stainless steel and are actually lighter than the stock exhaust system, though more effective. These cat-backs are made to produce a deep, powerful exhaust note, with the Loudmouth series +6 to +9 decibels louder than the rest. SLP’s varied range also includes 2007-2017 cold air intakes, with 3D CAD optimized designs that can add +10-15 horsepower in some cases (though some of these are NOT California legal). Many of these parts come with a limited lifetime warranty, and can be bought with free shipping when you get them through American Trucks.
