About SLP

Since 2001, LMPerformance has worked closely with SLP Performance to offer customers a wide range of performance enhancements to the American muscle car, the best known of which is its SLP Loudmouth muffler and SLP Camaro systems. With our SLP Performance parts line we have helped customers transform late-model rides into modern muscle cars like the Camaro SS and Pontiac Firehawk.

True to its name, Street Legal Performance (SLP) has a vision "to not just provide performance, but to do so with the best engineering practices and quality possible, far exceeding the industry standards." Impressively, SLP 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. LMPerformance carries SLP's best-in-class performance upgrades in the following product categories: TVS Supercharger Packages, Blackwing Cold Air Intakes, SLP Exhaust Tips, SLP Loudmouth Mufflers, Powerflo Headers, SLP Accessories, SLP Suspension, SLP Brake Kits and SLP Wheels. The range of applications offered by the SLP line is equally as wide. Below is just a partial list: Chevy Camaro, Corvette, GM/GMC Trucks and SUVs, Pontiac Firebird, GTP, G8, GXP and GTO, Ford Mustang and F-150, Dodge Challenger, Charger, Magnum and 300.
