    Founded in 1987, SLP provides a range of OEM-quality performance, appearance, and handling components for muscle cars and full-size General Motors trucks and SUVs. Primarily, it built performance engine parts for Chrysler-equipped racing cars. The company was the first to create an integrated emission legal (in all states) performance package for the V8 Chevy Camaro and Pontiac Firebird, which delivered significant performance gains and fuel efficiency improvement.

    This first 50-state emission-legal performance package manufactured by the experts at SLP provided a 50 horsepower gain, a one full second reduction in 0-60 mph times, and a 6 mph increase in its top speed. This is something that performance-focused companies never achieved before. Conceived by Ed Hamburger in 1970, today the company is among the leaders in the niche, a master in developing and manufacturing parts for American-designed high performance cars.

    Today, SLP has a net of facilities including a powerful research and development center and large manufacture plants. It focuses on quality performance enhancements for American muscle cars, constantly improving its technologies and providing the finest engineering practices, striving to exceed the industry standards. The company's innovations let thousands of customers improve the performance of their cars significantly and get completely new feeling from driving, unavailable with originally-equipped vehicle. Isn’t that a good reason to install its exhaust, engine parts, or air intake to get totally new driving experience? They are perfect high-performance add-ons to your vehicle that will provide an unforgettable driving experience each time you drive your car or truck.

    Apart from providing excellent quality, innovative products for your muscle car and totally unique upgrades for it, such as its famous supercharger packages and kits for the Camaro, SLP constantly widens its product line. Among its most demanded and successful products, you'll find cold air intake systems, high-power exhaust systems and headers, brake and suspension parts, body kits, various interior and exterior accessories, and many more. Just like its product portfolio, the range of applications served by the company is also wide. SLP engineers, designs and manufactures high-performance parts for Chevy Camaro and Corvette, Ford Mustang and F-150, Pontiac Firebird, GTP, G8, GXP and GTO, Dodge Challenger, Charger, Magnum and 300, GM/GMC trucks and SUVs.

    Not Happy
    It’s looks ok but no self installation instructions and required a muffler shop to install.
