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. Accesspeed is proud to offer SLP products to our customers. With our lowest price match guarantee, you will always find the best combination of price and selection at Accesspeed.

Long-Tube Headers

 

Do long tube headers increase horsepower?

Yes, long tube headers increase horsepower. If your state allows long tubes, this is a great investment in reliable performance.

 

Do long tube headers improve gas mileage?

Yes, from a technical standpoint. In most cases, fuel mileage will increase when you add long tube headers. The problem that Accesspeed customers have is keeping their foot out of the throttle because headers add so much horsepower.

 

Are long tube headers legal in my state?

If your state requires the OEM catalytic converters to remain stock, and in their original location, long tube headers are most likely illegal in your state, as these headers require modification or removal of the OEM cats.
