About SLP

Established in 1987, SLP has stood for quality performance enhancements for late-model American Muscle cars from the beginning, and 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 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 the industry standards.

SLP offers a wide range of performance enhancements to the American muscle car. SLP also provides best-in-class performance upgrades in the following product categories:

  • Blackwing Cold Air Intakes
  • Loudmouth Exhausts
  • Accessories
  • Interior
  • Suspension
  • Body kits

The range of applications served by SLP is equally as wide. Below is a partial list:

  • Chevy Camaro,Corvette
  • GM/GMC Trucks and SUVs
  • Pontiac Firebird, GTP, G8, GXP and GTO
  • Ford Mustang
  • Dodge Challenger, Charger, Magnum and 300.
