SLP Performance

SLP offers high quality performance enhancements for late-model 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. 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 and quality possible, far exceeding industry standards.
