SLP offers a wide range of performance enhancements to the American muscle car, perhaps the best known of which is its supercharger program. SLP also provides best-in-class performance upgrades for V8 equipped American Muscle Cars. SLP's initial claim to fame says it all: It was the first company in the performance aftermarket to develop and manufacture a 50-state emission-legal performance package -- specifically for V8 Camaros and Firebirds.
