Collection: Street Legal Performance

Established in 1987, SLP has stood for quality performance enhancements for late-model American muscle cars from the beginning, & it continues this commitment today. SLP's initial claim to fame says it all: It was the first company in the performance aftermarket to develop & manufacture a 50-state emission-legal performance package - specifically for V8 Camaros & Firebirds. True to its name ("Street Legal Performance"), the vision of SLP's part program is to not just provide performance, but to do so with the best engineering practices & quality possible, far exceeding the industry standards.
