SLP Performance
SLP Performance Products and Accessories
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 Car, Truck and SUV applications covered by SLP includes Camaro, Corvette, Firebird, GTO, G8, Mustang, Challenger, Charger, Magnum, 300C, Silverado, Sierra, Tahoe, Escalade, Yukon, Suburban, Avalanche and More.

Performance Exhaust Manifolds
Does an aftermarket exhaust manifold improve performance or fuel economy?
The aftermarket exhaust manifolds offered by Accesspeed are designed to increase power, acceleration, and fuel efficiency.
Why buy a performance exhaust manifold when I can buy headers?
While headers offer more performance, horsepower, and fuel economy than exhaust manifolds, many headers are not 50-state emissions legal. The performance exhaust manifolds offered by Accesspeed are all CARB-approved with 50-state EO# ratings, and they do provide increased power and fuel economy.
